it would be nice to see some paperwork.
VW has a well-established system of technical service bulletins (TSB).
and if there was some discussion on extending the interval, it seems not to have made it into any practice.
compare this with the timing belt interval, which increased a couple years ago from 120k to 130k miles. (as reflected in service schedules)
so the "made it up" comment is directed at whoever the op talked to.
there is a difference between some "is considering" semi-rumors which i suspect were put in some service newsletter or such, and a decision by VW to extend the interval
folks have honestly mis-remembered details, but the service guy at a dealer should base advise on facts. otherwise, why go see them.
(and for reference, the first time this came up, I had a chat with the VW customer service folks (online), which confirmed my suspicion that they exist only to steer you to the dealer. pretty much they said that the dealer can recommend extended service intervals, or lower service intervals. pretty much make stuff up.)
