Is this a red flag?

Hi guys, I'm new to the joys of Lego collecting and have a couple questions. Question 1: On Ebay and CL I'm seeing a lot of sets for sale that have opened boxes but sealed bags, I don't quite understand this. If you aren;t going to build the set, why decrease the value by opening the box in the first place? Is it possible people are building the sets, then somehow re-sealing the pieces back into their original bags? Question 2 : I realize that MiSB is the way to go as far as re-sale value is concerned, but if I also really enjoy building the sets I buy, does the "used" market still offer the ability to make some decent $$ too? If so, this might be the way I go so I can have my cake and eat it too. Thanks for any input!
