It turned out that a punter who was travelling from Euston to Watford
on a zone 1 - 9 travelcard season stored on Oyster was being told that
he was technically without a valid ticket because it hadn't registered
a touch at Euston. *(He wasn't actually PFed or anything.)

If it was a 1-9 Travelcard, the PFI was right, because Watford
Junction is not in Zone 9, it's in a special non-Travelcard zone.
Thus, he'd have had to register a touch in (and possibly an OEP?) to
pay the PAYG amount that would be due on top.
