Yes, bad habit:
Deceleration
Typically with motorcycles and in motor sport, the clutch is often used to facilitate the use of resistance from the engine spinning at high speeds to decelerate the vehicle more quickly, often accompanied with normal braking. This is achieved by placing the vehicle in a gear that would ordinarily be too low for the current speed and momentum of the vehicle and by partly engaging the clutch. When this happens momentum energy from the inertia of the vehicle is taken away to spin the engine as close as possible to its maximum capability. As the vehicle is decelerating the clutch can be further released to transfer more energy to keep the engine spinning as quickly as possible. Once the clutch is entirely released this cycle proceeds downwards through the gears to further assist deceleration. If the clutch is controlled improperly while this is being attempted, damage or extra wear to the engine and gears is possible, as well as the risk of wheels locking up and a subsequent loss of proper vehicle control.

You also run the risk of being in the wrong gear or too low of a gear and locking your rear wheel.
This guy explains it pretty good. And yes, he DOES say he stops by pulling the clutch, stopping then shifting down the gears. He does it when i do it, when a light changes red quickly, traffic stops abruptly, someone turns in front of you all of a sudden ... etc... and theres no time to engine brake.

I suppose I will ebrake a bit more. My bike has about 1500 miles on it. The bike sat for like 3 years so.. it probably isn't really broken in yet. I've heard of people not braking their bikes in until the 3-5k marker. I do exactly what he does in the video already... although I just keep the clutch in. I just remember what gear I am in, and downshift according to road speed. I don't like ebraking because it has to be ever so perfect to not get violently jerked around. I suppose all good things come in practice.
