I do not know which website this is from, but here is my take:
Training the European market is big business, and this is not the first time I have heard of schools rather unscrupulously tell prospective students they are getting a JAR (compliant - please don't notice this bit) licence. Translation - an ICAO licence. Hours is hours. Read it carefully - "Obtain both the JAR Compliant and JAA PPL - no extra course cost".
My reading of this is that you get their national PPL and during the training you will cover all syllabus requirements for a JAA PPL. Therefore, on return theoretically you could sit a JAA PPL skills test somewhere else without any further training costs.
It's not a JAR licence because no JAR licence is "issued immediately upon passing your final flight test"
Caveat Emptor
Edit. Don't however concern yourself with distinctions between JAA and JAR - they are often used synonymously, as you will see I lazily have above.
