Yes, I agree that that's what it means.

This makes no sense.

The reason I say it doesn't make sense is that you shouldn't be asking
for a long listing with ls -l if you want numeric ids, you should be
using ls -n. Instead of your alias, you should just be using ls -n
where you'd otherwise use ls -l.

The above is not flexibility; it's just different behavior. We need to
follow their specifications so things can be portable.
