I think this record is corrupted as there is a background star that was microlensed by a binary pair of foreground stars. This was detected as GAIA16aye and is the subject of the paper at http://simbad.u-strasbg.fr/simbad/sim-ref?bibcode=2020A%26A...633A..98W. This paper largely refers to the binary pair though gives a distance to the background (lensed) star. The background lensed star seems approximately the same as GAIA DR2 2032454944878107008.
There really needs to be two records, one for the foreground binary star and one for the background star even though they were very close together when the lensing event happened. It is not clear to me which object UCA4 601-089725 refers to.
