Rotated print sheet is not the only way to get a wrong back situation, although it seems to be the most common. There are times where a print sheet was run through the front of one machine and then they accidentally swapped the sheets with a different print sheet back before noticing it. Sometimes this even happened across sports or print runs.
I remember that a set like 1989 Topps football had some nonsports wrong backs. One of the early Magic the Gathering TCG sets had another misprinted backs issue.
