It's not entirely clear from the short post but it seems you object to the last of the Hussar unit types' name?
We have hussars in the eastern unit types at tech 9, 12 and 17. As with many unit types that get multiple versions it seems the original author was a bit short on words to say "More modern version of X".
As I am sure you know countries don't get unique unit types in EU so these all represent Hussars in general while specific Polish characteristics can be found in their national ideas (the best cavalry idea in the game as far as I know).
