In Einstein's case, this was often necessary, because Einstein used very strange naming conventions.

These symbols are easy to remember: all are variants of K, which is
the first letter of Koordinaten-system. The only difference is that
K denotes the coordinate system K, k denotes the coordinate system k,
K' denotes the coordinate syste K', and k' denotes the coordinate
system k'. All coordinate systems are intertial, and much else is
not said about them so needn'd be remembered.

The symbols K, k, K' and k' use two variations:

But 'primed' means what????

Nothing by itself. It is used to create a symbol that is different

Yes, but I have critized this, because any symbol used should have a meaning.

 The meaning "yet another coordinate system" is a meaning.

Thomas argument is of the kind: "Well this recipe show how to cook one
apple pie but I have a problem now: I want to cook two pies.".
