Paul is right. This happens because the differential is working as a
differential as well as a gear reduction unit. You can check what Paul says by
jacking up both rear wheels and turning them together.

Hi Mark,
Because you jacked up and rotated just one wheel, you need to make it go
two revolutions to get the accurate driveshaft revolution count. The
pinion and crown wheel tooth counts are also stamped on the top of the
differential carrier housing. This is on the outside.
