as mentioned, the stand will be past 90 degrees from verticle when extended.
I nearly had mine fall off the stand one time (luckily I was still next to the bike and I grabbed it). from that point on, I always pull the bike to the rear after the kickstand is on the ground, it makes sure that its fully forward.
when working properly, in order for the kickstand to retract, the bike actually has to be raised slightly as the stand rotates past the 90 degree mark. the weight of the bike will prevent this in normal circumstances. Again, park it with it in gear!
