Maybe the angle make the hose less likely to become strained while

That's about all I can come up with as well. Assuming that the supply
end of the hose has a straight connector and that the supply pipe
also has a straight connector meaning the joint is parallel with the
wall.

I think, as has been hinted, it is to encourage the pipe to form a
circular loop which can be safely pushed close to the wall.
