[QUOTE=sg3;3220816]that has to be incorrect. NJT is not running trains from Penn Station to Secaucus Junction and then using that same equipment to shuttle from Secaucus to the Meadowlands. I know they've arranged it so you don't have to but two tickets (even on the LIRR and Metronorth) but I don't think there is no change of trains involved at Secaucus
could be wrong though[/QUOTE]
It appears the shuttle runs from Hoboken, stops at Secaucus, then continues to the Meadowlands.
So, coming from Penn Station to Secaucus via NJT, you're right - you'd have to transfer.
If he went to Hoboken via the Path, though, there would be no need to transfer at Secaucus.
