No, that's wrong.

If 'x-Achse' ('x-axis' in German) was named 'X', then 'X-Achse' would be 
in long form:

'x-Achse-Achse'

because the text 'x-Achse' is equal to the string 'X' by this definition.

Combining two strings is like putting them together and we get:

'X-Achse' = 'x-Achse' + 'Achse' = 'x-Achse-Achse'

And Einstein did in fact use 'X' as name of the x-axis of system K.

The system k had tall Greek letters as names of the axes:
Xsi, Eta and Zeta.

Here Einstein made an error, too, because once defined these names had 
to be used.

But Einstein used also X, Y and Z as names of the axes of system k, too.

He also used X, Y and Z as components of the electric field strength vector.

This culminated in twice the same symbol 'X' in the same sentence, but 
with two different meanings.

In my role as a hypothetical professor, who had to write corrections, I 
freaked out a little at this point and wrote a big red 'F' on the first 
page on the paper.
