It's funny when you compare the two (and I'm pretty sure I've accidentally restarted a timer that I meant to stop because of the muscle memory I have around alarms), but it makes sense to me. For alarms, the biggest, most obvious button absolutely must be snooze, not stop. The plausible harm caused by accidentally stopping when you meant to snooze is very high: you miss an interview, final exam, court date, or are late to work one too many times. The plausible harm caused by accidentally snoozing when you meant to stop the alarm is orders of magnitude lower -- you are embarrassed when the alarm goes off somewhere quiet, maybe you get kicked out of the movie theater. For timers, 90% of the time, you want to stop the timer. Another 5% of the time, you want to start the timer again for a different amount of time. (How often do you put something in the oven for 35 minutes and then discover it needs another 35 minutes? Usually you just need a few more minutes.). Only occasionally do you want to restart the exact timer you just finished. It's a nice feature to have, but it's appropriate to make it subtle.
