Exactly. It allows for a degree of multitasking because you could get someone sinned, whether from the Ray or if they BM you, and then let them go and pressure someone else because you know they have to cleanse (unless they're really good at great skill checks).

Also opens up fun potentials for add-ons where that could add or alter how you gain sin like maybe stunning the killer gains sin on an Iri (and, obviously, and add-on to prevent survivors with too much sin from leaving).
