Stan - whilst what you say is correct - it's worth pointing out that ANY FIXED WING FLIGHT TEST will count in lieu of the 1 hour dual requirement with a JAA instructor for SEP revalidation purposes. Emphasis on fixed wing - rotary test doesn't count.
MPA Instrument Rating on a B747 will count - but you still need 12 hours in SEP aircraft (the flight time doesn't count - just the "test" aspect).
