That is not accurate. This is hiding the special meaning of the
'words' variable, only locally. "Suppress" denotes that the special
meaning of 'words' is gone forever, even on outer layers of the call
stack.

That can be explained in shorter form:
# Workaround for versions < 4.3.12
The word workaround denotes that there's a bug, and by limiting where
the workaround is needed, it's obvious where proper fix is.
All this can be explained in this sentence:
# workaround zsh's bug which leaves 'words' as a special variable in
versions < 4.3.12
What is the need to change that?
