Where a roll's own content ends, as far as its perforations say.
This is a question about the paper, not about the mechanism: it asks where
the rewind is punched, not when the rewind pneumatic takes hold. The second
is a matter of valve lift and belongs to whatever performs the roll. Keeping
them apart is what lets collation and counting ask this without an emulator.
