I believe what she's referring to as "terminal ends" are where a run of fabric is joined to another run of fabric at the factory. This is usually characterized by large stitching holding the 2 ends together. It is not the same as selvedge or end of bolt.
I have seen this before with orders from Connecting Threads, but as I said, I ALWAYS get more than I ordered. The piece with the "terminal end" isn't even counted in my order, I usually get it for free.
