I was also taught this in college (early 60's) or maybe even high school.  The 
distinction went out of vogue some time later (70's??).  Maybe what Jim saw was 
someone trying to bring it back.

The distinction between temperature differences (kelvins) and a point on the 
kelvin *scale* (e.g. 273.16 kelvins) was taught to me by my first professor in 
General Physics.

He used the terms "kelvin degrees" and "degrees kelvin" to make that 
distinction.  There is a need to distinguish "delta T" and "T" in writing if 
not 
in formal symbols, I believe.  


He was not a textbook author.
