I'm not so sure, but having said that it's been a common theme since they launched TT:120. There have been other "schoolboy errors" of varying magnitude over the past couple of years, many of which, like this one, could have been nipped in the bud by having someone on their staff who knows the subject and can proof-read/check their stuff before publication (written/verbal/video). Unfortunately that doesn't seem to be the case so we will continue to see stuff come out where most of us will just give a quiet "groan" and (again) ask them to clarify, like in this case. It's just a reflection of the people they employ, who, whilst they may be fine at checking every detail is correct down to the last rivet, don't seem to be actual model railway enthusiasts , especially those in marketing and who do the publicity.
Frustrating, yes, end of the world, no!
