Not quite sure a follow but if you're asking if the itch version will continue to be updated after the steam launch the answer is obviously yes.
If you're asking if you get a steam key after purchasing here the answer is obviously no.
Sorry for the bad formulation.
my question was if the need to pay for every Single Update this game gets?
Or if it is a 1 time pay - get every Update
I hate that this is even a thing tbh. You pay you own the full game. You won't need to repurchase it.
