I can actually think of reasons why they changed this scene. It's not the fact that they're half naked, it's the fact that it's suggesting that if he got there any later, they would have been tentacle raped.
It's still shitty they still changed it in the uncut version. Rape his something that happens in this world.
As for not dodging the punch.. That was shitty of Bones. They took what was actually pretty funny, and made it stupid with that stereotypical "ROFL STRONG WOMEN XD".
