From that URL, except immediately above the anchor (emphasis mine):

    Patterns used for filename generation may *end* in a list of
    qualifiers enclosed in parentheses.

Since your instances of (...) do not terminate your patterns, they
are interpreted as delimiters for grouping [*].  Another example:

    % touch /tmp/foo
    % print -r -- /*(p)/foo

Clearly (p) is not acting as a glob qualifier here, as /tmp is not
a FIFO.  That pattern is equivalent to /*p/foo.

I'll leave that for someone else, as I don't have any suggestions
at the moment.
