A cross-track burn rotates the orbit plane rather than changing the period, so separation appears immediately at the burn point rather than accumulating.

Low-thrust system — the burn spans a meaningful fraction of an orbit, so it is modelled as finite rather than impulsive and the achieved delta-v is direction-averaged.
