So that the programming in the clock only needs to look at one number instead of 2. For example, if your alarm goes off at 10:02 and you hit snooze, if the alarm was to then go off again at 10:12 (ten minutes later) it'd have to keep an eye on the second 0 digit and the last digit (the 2) so that when the 2 rolls around again, but the 0 turns to a one, the alarm goes off and you get a 10 minute snooze.

To make things easier, they just set it at nine, so when the very last digit (the 2) goes down one (so it's a 1, so 9 minutes have passed) the alarm goes off. Very simple programming in comparison.
