Yes. The idea of this serial number is that when in two years you
encounter a patched copy of glob.m4 which appears to be a mix of serial 3
and serial 4 in gnulib, you are able
  1. to see that it's a patched copy (because you know against which
     version to compare it),
  2. to find out whether some patches were added to serial 3 or some
     patches were reverted from serial 4.
