I think I may know what you’re talking about.  First, the way the exercise is printed out is confusing. 

There’s different ways to do this exercise.  You can practice each measure so that you play quarter notes on down bow, then up bow, then eighth notes down bow, then up bow, or alternating throughout, first starting on down bow, then up bow, etc.,

Second, I know when I first started, I had a hard time with slurs.  I found that I got confused with groups of notes when I was concentrating on where I needed to change my bow direction. 

I think having the left and right hands doing completely different things is confusing to our brains!  My teacher refers to this as “Kerflooey” – when your one hand is doing something, & your other hand is getting screwed up. 

Since the Red Violin video above is referenced, & she plays it alternating down & up bows moving through quarter, eighth, & 16^th notes, I’ll gear my suggestion toward that: 

1. Play the 1^st 4 notes (measure 1) on the down bow only – slow (quarter note speed), then stop. Reset your bow to play these 4 notes again on the down bow again, & then stop.  Stopping allows you to think about what you're doing. Repeat this several times.
2. Play the 1^st 4 notes (measure 1) on the up bow only – slow (quarter note speed), then stop. Reset your bow to play these 4 notes again on the up bow again, & then stop.  Repeat this several times.
3. Now play measure 1 again like you did in #1 on down bow with quarter notes (1, 2, 3, 4) & stop.  Reset bow to play down bow again, & play measure 1 with eighth notes on the down bow (twice the speed , playing the 4 notes twice 1 & 2 & 3 & 4 &= A B C B  A B C B), & then stop. Repeat this  several times, first playing the quarter notes down bow, reset, then playing the eighth notes.
4. Do the same as #3, but now do it on the up bow.  Repeat several times.
5. Now play measure 1 four notes (quarter notes), down bow, & stop.  Then play measure 1 eighth notes (like in #4) on the up bow, & stop.  Do this several times, alternating down bow 4 notes-stopping-then up bow for the eight notes.
6. Once #5 feels comfortable, take out the stops.  Play down bow quarter notes, up bow eighth notes (1 2 3 4   1 & 2 & 3 & 4 &   1 2 3 4   1 & 2 & 3 & 4 &  . . .). 

You may need to do this over several sessions for it to become more comfortable doing the quarter & eighths.  Then work on including the 16^th notes.  For the 16ths, you may need to break it down in a similar way since it is difficult to do a 4 beat 16^thnote slur to start with.

7. On down bow, play 1^st two beats of 16^th notes (1 e & a 2 e & a – ABCB ABCB) stop,  & then up bow the next two beats of 16^th notes (3 e & a 4 e & a – ABCB ABCB).
8. Now do down bow quarter notes, up bow eighth notes (like in #6), down bow 16^th notes for 1^st two beats – stop- & then 16^th for 2^nd two beats.  Once that is comfortable, take out the stop.
9. Once you are comfortable with #8, then try to do full 4 beat 16^th notes for the measure on down bow (ABCB ABCB ABCB ABCB), & up bow.

10. Once you’ve done all that,  put it all together for measure one –

- quarter notes on down bow,  followed by

 - eighth notes on up bow, followed by

- 16^th notes on down bow   then

-  quarter notes on up bow

-  eighth notes on down bow

- 16^th notes on up bow

Then go to measure 2. . .   Might be helpful to do all of #1 -10 with measure 2 just like above since your left hand is doing something different.  Or you can just do #10 above, & then move on to measure two, following the same pattern of alternating bow on each type of note (quarter, eighth, 16^th) and moved through the exercise that way.

Hope that isn’t too confusing.
