I think it depends on why you're skipping it. If you need to do some research and you don't want to break up the flow of your writing, that sounds like a great reason to pause and come back.
For me, it's been a bad idea because I tend to skip over passages that are just, well, hard. It's an intimidatingly important section or something hard to put into words, so I figure, "I'll come back to it later. It's already hard enough to write this first draft! I'll get to it while I'm in edits."
It was a good thought, but didn't work out at all for me. Those sections are just as daunting and difficult later as they were the first time. Even worse because I've lost the flow and the mindset I was in during the first draft. Every section I skipped and came back to later, I ended up kicking myself and thinking, "Argh! Why did I do that?"
I'm glad I gave it a try, but never again. (At least not for those reasons) Try it yourself, but realize it may be tougher to come back to the second time than it was the first time. Learning your own style of what works for you can only come by trial and error. Good luck to you!
