This statement is a big confusion for users and is a pet peeve of mine.

There is no such thing as calling a USE flag "local" or "global" except
for where the description lies.

If they want to enable a flag to apply system-wide, then it does not
matter where the description is. To users, a USE flag is a USE flag.
