I think I confused it with the use of $value in ${if acl{...} ...} which
seems to have no such stacking regime, or at least it is not
documented. Is that by design and why?

Be that as it may, this overloading in itself feels like a mistake. The
ACL condition should have set $acl_value or something like that. Sadly
it's probably too late to change it ...
