That you're more likely to twist the chain on a multispeed bike upside down roadside is common knowledge. I'm a little shocked that I need to spell this out on a bike forum.
I have some bikes that are a lot easier to get the wheel seated properly upside down, but I will only turn it upside down after I have the chain properly looped over the rear sprockets.
