See the GNU make manual section "How Patterns Match":

           When the target pattern does not contain a slash (and it usually does
        not), directory names in the file names are removed from the file name
        before it is compared with the target prefix and suffix.  After the
        comparison of the file name to the target pattern, the directory names,
        along with the slash that ends them, are added on to the prerequisite
        file names generated from the pattern rule's prerequisite patterns and
        the file name.  The directories are ignored only for the purpose of
        finding an implicit rule to use, not in the application of that rule.
        Thus, `e%t' matches the file name `src/eat', with `src/a' as the stem.
        When prerequisites are turned into file names, the directories from the
        stem are added at the front, while the rest of the stem is substituted
        for the `%'.  The stem `src/a' with a prerequisite pattern `c%r' gives
        the file name `src/car'.

If I'm understanding your description this explains the situation you
