Situational superko can be defined in terms of not permitting a
cycle in the game-tree, thus always preserving its acyclic nature.
[Positional superko, IMHO, has no such elegant rationale.]
Agree, situational superko seems to me much more
elegant. For example, pass allways makes positional
superko (of course pass is an exception).

But then, wouldn't passing twice be a situational superko? That is an
obvious exception there too.
Ko rules, and superko rules of all kinds, restrict where a stone may be
played on the board. No ko or superko rule ever forbids a pass.
