Hello Claude, Indeed, if we had to choose a new word for these kind of dials "bi-style" or "double style" would be a good choice. ( And then also "mono-style" if only one style is present as a pole style or vertical style or irregular style )
But the bifilar dial was invented by Michnik in the 1920's and he used the German words "bifilar Sonnenuhr". Because of this historical event I strongly vote for the original term bifilar dial. Fer.
