To stick to the particulars of the exercise, yes; part of the exercise is to see how the two different pieces of music impact against the choices you made.

But as Lola mentioned: For all of these exercises, the rules are hard and fast, unless you don't want them to be :D Some people work best with really specific restrictions, others work best as rule breakers <3

So if you really have a strong desire for creative purposes, to rearrange the clips for some particular reason - there's no grade, you won't fail :D You will just have a different experience of the challenge.
