Thomas, I have in my collection some stamps that are supposed to be tagged but are not. I call them "tagging omitted". I also have some that are untagged. There is a difference.
There are also a few stamps that were meant to be untagged but were tagged by mistake. The example that comes to mind is the 3-cent star coil of 2002. In this case the mistake was the use of prephosphored paper for many of the stamps. Both the untagged version and the tagged error are common.
