If the way is not closed, only the rules in the lines file are used.
If the way is closed, the rules in the lines file are used before the rules
in the polygons file. In this case the rules are combined are
if they were placed in one file.
So yes, if you delete a tag in the lines file, the tag is not visible in
the rules of the polygons file.

A special case: Some ways are only passed to the polygon rules
or only to the lines rules, this happens for ways that are members
of mp relations or created by mp-processing.
