Yea, it's f@#king backwards mate
As Joris said, I think the reason is that they're not sleeve with clear plastic on the outside. The pen pushers here that make the rules want the plastic sleeve to stop the potential of the stainless steel braided hose rubbing on something and subsequently wearing through... hahahaha what a crock.

I'm sure if I took the original hose and one of my new illegal in NZ good ridge ones and rubbed it with a stick for a few hours, the rubber one would wear through first
