From the Focus Points from Multiple Sources sidebar on the Focus Spells section of the CRB p.300:

[...] For instance, if you were a cleric with the Domain Initiate feat, you would have a pool with 1 Focus Point. Let’s say you then took the champion multiclass archetype and the Healing Touch feat. Normally, this feat would give you a focus pool. Since you already have one, it instead increases your existing pool’s capacity by 1.

The Healing Touch feat however reads:

If you don’t already have one, you gain a focus pool of 1 Focus Point, [...]

So what's the deal here? Is the Focus Points from Multiple Sources text outdated? Or do you still get a Focus Point because it counts as a separate source of Focus Points and you don't already have one from that source? Is there another reasoning that I'm currently not thinking of, why you'd still get a Focus Point? Because if so, that could have wider implications for Focus Point gains from Archetypes.

Edit: seems this question has already been answered: https://www.reddit.com/r/Pathfinder2e/comments/ew2qu9/focus_points_from_multiple_sources/

I'll leave this thread up for visibility and further discussion.
