Different snapping, at least to what I’m used to. The snapping Windows offers is half and full screen windows with a keypress (or dragging against a wall). Mac does offer something similar, but only for full screen/split-full-screen mode.
Be that as it may, the post I responded to was commenting on the absence of a feature that isn’t absent. Wether you like or are accustomed to its behaviour is a different matter.
(Not making any claims about the usefulness of either feature)
The fact that OSX would have a feature called "window snapping" that isn't really the same is similarly mind boggling.

So does macOS[1] (and iPadOS).
You lose the menu bar and dock to full screen mode (they're hidden, more specifically).
Discoverability could use some work.
