Maybe it’s just considering de facto control? Israel currently controls the whole Egypt-Palestine border, so there’s no land controlled by any form of Palestinian government that has a border with Egypt
Edit: or it’s an artifact of the “exclaves have otherwise been ignored” part, if the West Bank is considered the core and Gaza is an exclave of that
The West Bank contains both the claimed capital of Jerusalem and the seat of government of the Palestinian Authority in Ramalla. This means Gaza is an exclave.
