Probably, i didn't explain it clear:
My thought: you making A event twice: A with vanilla kink and A' with BDSM kink. They are mutually exclusive, but has very same outcome. This way player will do A event but with the way he prefer.

That's not the same event though, even if you use deceptive variable lettering. There's quite a difference between the same event and the same outcome.
And that's only if I was willing to accept the false idea that the outcome can be the same when you're clearly continuing on a path with a different history of events - which I'm not.
