VOR...you are right insomuch as you cannot COMPLETE a JAA I/R outside the relevant airspace - but Comair can give you a very professional start towards it (and save you some money in the process).
Comair are teamed up with - I think - one of the schools at Coventry to finish off your training in the UK.
Comair have the JAA rated staff to do this - NAC don't (yet!!)
It's not a scam - Flight Safety started it, Pan Am did it, Air Safety did it, West Michigan still do it - and the unmentionable school on Florida East Coast still does it...as does EFT @ Ft. Pierce, Florida.
Now - despite what any school advertises - you should allow at least 15 hours (maybe 20) of the 55 required to finish flight training in the UK.
Do the math - you can do some 35 to 40 hours here in Florida - does it save you enough time and money to justify the tran-Atlantic flight and accommodation.................your call.
