They gave Vingegaard Vélo d'Or for the Tour, but in 2020 they didn't give it to Pogacar for winning the Tour![]()
There's no a specific criteria por Vélo d'Or. They're journalist subjetive votes.
So, indeed, another stage/GT GC contender got it, not the one winning the Tour. Indicating winning the Tour after all can sometimes be considered less, compared to other stage racing achievements in the ongoing season. Furthermore you can pretty much win everything in "classics", but you highly likely won't get it if some stage/GT GC specialists has a reasonably good season.
