Back in the days of class 1 2 & 3, it was possible to drive a drawbar on class 2 or 3. When the classes changed to C or C+E, if you had been driving drawbars you could get a C+E, but restricted to drawbars. Code 102 only applies to these drivers. If you pass now in a drawbar you get the same licence as some one who passes in an artic. Definition of a C+E licence on DVLA web site doesn’t differentiate between the two.
