Almost none of his variables were defined properly.

But Einstein wrote actually:

"If we place x'= x − vt"

'...we place ...' sounds like he meant some sort of position of 
something, which is placed there.

 From the context would fit 'position of a mirror on the x-axis of K', 
because a mirror could be placed there.

So far, so good.

But: if we place a mirror there, the equation does not fit!

This is so, because x is belonging to K, too, because it is a variable 
in Latin letters, which belong to K.

 From the context of x, we are able to assume, that the position of an 
event in K was meant with x, which has a certain x-coordinate, why x has 
a fixed value in K

But if we subtract v*t from that x, the position x' would move, while 
the placed mirror shouldn't.

So: what else was actually meant?
