Yeah, sure looks like a typo to me too.
I temporarily changed the Assert to be "==" rather than "<=", and
it still passed check-world, so evidently we are not testing any
cases where the descriptors are of different lengths. This explains
the lack of symptoms. It's still a bug though, so pushed.

Yeah, we've agreed to join the 21st century to the extent of allowing
local for-loop variables.
Thanks for the report!
