No, this is actually true. All the animated series created by Masaki Kajishima take place in different universes in the same multiverse/omniverse. Dual and Seikishi Monogatari even had it as a theme to jump between them, and parallel versions of the Dual characters showed up in the Tenchi Muyo GXP novels. 5 dimensional=planar time=all parallel timelines=multiverse as far as I understand the concept.
