If you shut if off before the motor has a chance to wind down you probably wear out the engine more and the transmission doesn't get its last gulp of fluid (aka for dingy pulling it recommended idling in neutral a while before pulling)
Mine sometimes did that as well (stumble or start hard), the car does not like being shut off then turned back on in short periods, especially if the motor is cold. Generally I only shut off when it would be off a fairly good while, the one coast down takes several minutes. I also tended to use engine off more when temperatures were warm because the issue seemed to be mostly temperature related.
Also I have a feeling you would find the car would do the same thing if you drove a while (engine not warm) came to a stop, put in park shut it off then 20 seconds later turned it back on.
I am uncertain that it actually damages anything, it just isn't tuned quite right for a while (too much choke), also its good practice to turn on a little earlier than you need to go so everything is filled up and ready so to say.
