I was thinking at a higher level of abstraction.

Or rather, a lower standard of epistemic accuracy.

PUA skills pertain to influence by males over female behavior using methods that include operant conditioning (including reinforcement). It does not follow that all instances of influence by a male over a female using operant conditioning is standard PUA methodology. In fact this example is significantly different to the kind of application we see in standard PUA. This is unsurprising - after all, we got the example in question when Konkvistador took a wife-influencing-her-husband example and substituted roles.

I prefer the grandparent:

There is a relation, I suppose, in as much as both are about a male influencing a female subject and both rely on principles of human or mammalian psychology. They differ in goal and (so) differ in the specific kinds of tactics.
