Would it be clearer to use this?

    git p4 commit |\
    grep -q -v "git author.*does not match" &&

With your original change, I think that if "git p4 commit" fails, then
that expression will be treated as a pass. What we want is for "git p4
commit" to pass, but the string to be missing.

(I would have used "--invert-match" rather than "-v", but it seems
that's not supported on Solaris).
