What do mean by "The markings are WRONG"?"

I thought that "I believe the markings are derived from the requirement that above a certain rating the terminals are rated for 75 degrees." explained why the markings are wrong.

Any device that passes the 75 degree test passes the 60 degree test by definition.

The people who determined what markings should be on the device made a mistake.
