In this case the relative distances to the 3-sigma zones weren’t as large as some events. There’s uncertainties in the asteroid’s orbit (hopefully to be improved with Gaia DR3) and there were no Gaia flags against the star, although it had no RUWE value, which probably contributed to the shift.
There’s a recent discussion of RUWE here:
We’ll continue to have some significant path shifts until the final Data Releases from Gaia minimise the uncertainties in asteroid orbits and stellar positions.
