The curve is probably where it hits max junction temperature.
There are two limits in this kind of specifications:
1: junction temperature,
2: where sum of delays exceeds 10 % (or any pre-defined fraction) of the period.
The curve represents the lower one.

Thinking about these dinosaur FETs is pointless, since there are cheap, small, powerful and fast ones too. The weakest link is the PCB. :-)
