so, I thought I was imagining this but I have confirmed it on multiple occasions.
I have my alarm set for 6:40am. if I hit snooze, it goes off again at 6:50am (and labels it 6:40am). if I hit snooze a second time, it never goes off again.
this is most certainly not the way it worked on the 935. moreover, I have been awake enough to see that It clearly has a button at 6:50am that says "snooze" (the down button).
