No, you don't.  You overlooked the fact that I said "by default".
Also you overlooked the fact that I said this depends on the order of
the various rules.

So you can either play with the order of the rules, or you can choose to
use a non-default behavior (see OVERRIDE in font-lock-keywords's
docstring).
