Yeah, that's bad 
I recently did something similar right in front of a local dealership/service center. My foot slipped off of the kickstand and didnt move it. I thought it was down and went to lower the bike. By the time I realized it, the bike was passed the tipping point and I was swinging my leg over. I kept it from falling and making impact, but had to rest it on the floor to reposition my hands to get it back up. Luckily there was only one other guy outside to witness...
