Maybe i'm missing something but take this example:
Page "Westplex" redirects to "St._Charles_County,_Missouri": https://quarry.wmflabs.org/query/43707
It apparently does so since 2018: https://en.wikipedia.org/w/index.php?title=Westplex&type=revision&diff=828554258&oldid=827301936
Yet in pagelinks: https://quarry.wmflabs.org/query/43706
