I didn't learn from videos, I don't really own any. If you had the opportunity to watch Ray Hunt or Buck Brannaman or any other quality trainer start colts, you would see an arena full of them being worked loose. This is pretty common stuff, the reasoning behind it is to keep the colts and riders out of trouble by keeping them working/distracted.
