It happens.  Particularly if the discipline is botched for some
reason.  The jitter is low so that's a good sign.  However I think
he's using a BeagleBoard not a BeagleBone of either flavor, certainly
not a Black since the ntpq output is reported as a year ago -- not
that that should really matter for a simple PPS clock.
