These are both tricks that actually work. I find using a 20lb propane tank and cracking the valve open a little works better than chopping into a propane line. (you turn the tank upside down so liquid propane drips out instead of blowing vapour)
These tricks apply to working on equipment which alot of forum users will never see. For example trying to install walking bushings into a heavy duty suspension is where the shrinking of the bushings comes in handy. If you have never done it you can not understand how difficult it can be. Also you brits will never see 40 below but at the temperature you can pack propane in a bucket.
