Hey, Eyedea!

Yes, you can use Page Jumping to jump to previous pages, but it isn't advised.

See, you could potentially set your respondents inside of an infinite loop, and your survey's “Back” button may do some strange things if you jump from page 5 to page 2, then click the back button, because it would be going 'back' to a page in front, which is not how the survey is intended to flow.

I would recommend ordering your pages in such a way that you don't have to use Page Jumping to go back – make questions required, or use jumping to skip pages you don't need, or Show/Hide controls to skip questions you don't need.

Hope this helps!
