You should keep in mind, that it is absolutely impossible, that an 
author requires from the readers, that they would marter their brain to 
develop, what actually the author should have written.

Einstein himself had to write, which coordinate systems were used and 
for which quantities. These quantities need to be defined properly.

But in contrast to common standards, we are now discussing the question, 
whether the mirror moves (or not) in system K.

This is an information, an author needs to provide.

We are now discussing this question on the basis on other constraints 
like other equations or descriptions in the text.

But I have tried hard and found no possible setting, which violated non 
of these constraints somewhere.

Now we had to declare this an error of the text and not ours, because we 
already did, what no author could rightfully demand, and tried to read 
the authors mind from rare hints, but with no success.
