NEO 2T, is it directly compatible with MTB 135 mm bikes or not?

Maybe my English is not good enough and maybe I don`t understand well but in NEO 2T web I can read:

"Directly compatible with 135×10 mm axles" but also: "...for 135x10 bikes you'll need an additional adapter..."   (which costs around 45-50 € or $, BTW).

My bike is MTB 135x10, so just in case, I bought that 49€ adittional adapter before receive my neo 2t few days ago and it has nothing to do in shape, size and number of pieces with the "in the neo 2t box" adapter from factory.

I mount the factory 135 mm adapter and it seems to work fine but this confusion makes me wonder if my current configuration is te correct one.
