Their written description notwithstanding, LyX is a hybrid between WYM and WYG. It bundles up standard blocks of source code and hides it behind graphical objects which resemble the final product.
I believe that description is aimed at former MS Word users who don't even know the WYM/G distinction exists, not as a definitive membership claim by LyX.
