AFAIK stems from mathematics where you write things like

{y | \forall x \in X : \forall y \in x }

And so many people consider it pretty natural/intuitive. After all, we read
from left to right, and making something depend from something yet to be
introduced is counter-intuitive in my book. YMMV though.
