It's weird cause I always disconnect it like that... I did it twice... mine didn't spray with the towel wrapped around it... also I disconnect the top side (hose from the engine first) then the other. However I did let the car sit a few hours before this, mostly cause the engine is hot and that's a fire hazard.
You are giving advice that can get someone hurt. If the pressure in the fuel system does not drop as fast as yours, when the hose clamp is loosened, fuel sprays out immediately. Following your advice someone can get fuel in their eyes. If they don't allow the engine to cool before loosening it, there can be a fire or explosion. Even if the probability is low, it is a chance that should not be taken.
Suppose someone gets hurt taking your advice. You are liable to get sued.
The factory service manual is emphatic about releasing the pressure before working on the fuel system.
