QuickZoom does not zoom back to mouse pointer position

I’m on a mac and have noticed that the quick zoom (Z key) works for zooming out but I haven’t a clue how it is picking a spot (same spot) to zoom back into. I thought it was supposed to zoom back in where the cursor is (per video here: https://player.vimeo.com/video/242045455?title=0&byline=0&autoplay=1)

hope this helps!
