Or this is an alternate future Ben who didn't have said incident when he was 20?

I doubt any Ben 10K we've seen is actually Ben's future (it's stupid to 100% confirm the whole future of someone unless it's in a series about their future) and it's totally possible that this Ben didn't have that incident happened.
