So, at my open water course this was actually the taught method of securing your octo. It's also recommended by James from Scuba diver magazine, IIRC. I don't prefer it (I have a silicon holder that slots around the mouthpiece which came with my BCD, and one of those necklace things for my primary), but imo, I don't think it's doing much damage. Hoses are meant to bend, and so long as it's under pressure, it shouldn't kink too much.
