The difference is villain limp calls Q-8 and is described as a station so seems passive rather than aggro in not letting go of pairs. Here he's bringing the heat with a big raise so no evidence this is a single pair hand. I think we're being asked to play for stacks with one pair and I don't like that this early. More inclined to think villain has set than fd as well.
Agree with this and everything dave has said.
Think people massively underestimate a passive station's hand range when they suddenly get super aggressive.
