Is anyone out there familiar with minimum line guarantee?

I'm stuck in AMS now (I know, woe is me), with a 48 hour layover that's become a 98 hour layover. My original trip was due back before the end of the month, but the reroute is a transition trip.

My original monthly projection was 67 hours. Now, since the new trip pays mostly next month, my projection is 56 hours. I haven't modified my line from what I was initially awarded. Does the line guarantee of 65 hours apply here? The way I read it, the answer seems to be yes, but a second opinion is always nice...

Thanks. (I don't want to make a call to ALPA; they've got more important things to do right now.)
