Anyone know why you can not use NLC (New London, CT) as a "stop" on a multi segment trip?

I many times travel on a multi from KIN to OSB. However, if I attempt to put in KIN-WLY-MYS-NLC-OSB for a 4 segment multi, it gives me one train from KIN to NLC - but the next train from NLC to OSB! But if I input a 3 segment multi for KIN-WLY-MYS-OSB (through NLC!), I can do it on the same train!

Normally, this would not be a problem, but I am losing a segment each way! And with the multiple promotions going on, that's 400 to 1200 points per trip!

I understand dwell time in places like NHV (2-5 minutes), NYP (15-30 minutes), PHL (3-10 minutes), and others. But there is none listed for NLC on any schedule! So why am I losing these AGR points?
