JO pool play EP

[CecilOne]

From the March “clarificatons” about JO pool play:
An EP can be a pinch runner for anyone.
However our Re-entry Rule would still be in effect.
The EP would be considered a substitute for the person they are running so the person who they run for and the EP running will have one more reentry.
The EP is now tied to that person and can only pinch run for that person.
Once they have used up their re-entry they still may bat and play defense but can no longer be a pinch runner.

Presumably, the EP does not use a re-entry when afterward batting in her original EP spot, as she never left the game.
That means she can run for that other twice.

Example, Annabelle an EP, runs for Beatrice. Later, Beatrice is replaced by Clarissa.
1) Does “can only pinch run for that person” mean Annabelle cannot run for Clarissa. It would seem so, because it says “person”.

What happens if the "anyone" spot comes up again and the "anyone" player has already used re-entry?
2) Continuing, Beatrice re-enters and bats again.
If Annabelle runs for Beatrice again, does that mean Clarissa must replace her next time that batting spot comes up?

3) What about if no Clarissa or other subs, is Annabelle trying to run for Beatrice again an illegal re-entry for Annabelle? It seems so.

OK, 2 & 3 might be TWP, but is anything with a new rule after last year's version?
