It may be relevent that there is some competition on this route off
peak. There are FCC trains to Kings Cross and (slower) NXEA trains to
Liverpool Street. FCC own the "Route Any Permited" flow but there are
also "Route NXEA only" tickets offered off peak.

Yes, I think tim might be getting muddled/sidetracked by the existence of
these fares.
