It sounds more like a leaky flip-flop.

Yes - I think so. Though (1) I'm not sure why you say "leaky" (I haven't noticed any claims that the device "leaks" state over time), and (2) it's substantially smaller in size and power needs than a single transistor, whereas a flip-flop requires five or ten transistors (I'm not sure exactly), and (3) it keeps state while powered entirely off.

I said leaky because it will conduct the “wrong” way, it’s just not so good at doing so. (And, if I understand correctly, if you keep doing that it trains to go that way). A flip-flop requires but two transistors, and if you make it with MOSFETS (ideally, with infinite gate resistance) the thing can remember its state on power-down - essentially nonvolatile memory.
