Sorry to be pedantic, but is it actually 50 here now?

The sign existing Ozolnieki North ends the city limit, so it becomes rural 90:

It then only becomes 50 white city limit before first residences of Jelgava: https://www.mapillary.com/app/?pKey=1310948489592910&focus=photo

Is the anonymous note implying that the whole section has been recently changed?
