Can anyone explain why the cables connected to L1, L2, L3 and L4 must be with the same lenght?

Where did you find the information, that they have to?

In the Shelly 4 Pro User Guide.

Wow....

For me this seems to be a mistake during translation...

The cables connected to L1, L2, L3 and L4 must be the same line (phase)!

That makes sense. If so, they should correct it.
