You can choose differently for nested actions - eg, if you flip the Blight card and it has immediate effects. (Example: You play Insatiable Hunger of the Swarm, and count all of your Sacred Sites as Beasts. It adds Blight which flips the Blight Card, revealing the one which destroys 1 Beasts on each board. You choose to not count any of your Sacred Sites as Beasts for that. You then continue resolving Insatiable Hunger of the Swarm, and your Sacred Sites count as Beasts for it.)

That being said, you can count an Incarna on the island as Presence for the purpose of checking where it moves. So, e.g., Wandering Voice Keens Delirium can count its Incarna as the Presence it's moving the Incarna to, thereby moving the Incarna to the land it's already in (which would then add Strife with Spread Tumult and Delusion).
To expand on the situation, a land contains one Presence from Rising Heat of Stone and Sand, one Presence from another Spirit, and a Town with 1 Damage. "Entwined Power" is used between the two Spirits, and then Rising Heat uses a Power that requires a Sacred Site there for targeting. Even though targeting the Power is legal by "Entwined Power," the land only counts as a Sacred Site for Targeting, not for the Special Rule "Blistering Heat."

Nevertheless, Roiling Waters Bleeding deals Damage if repositioning a piece on the island that already counts as a Beasts, whether that's the Incarna of Breath of Darkness Down Your Spine, the Presence of a Spirit under Settle Into Hunting Grounds, or a Sacred Site belonging to Many Minds Move as One.
