A login page and a game board view would be mutually exclusive, but 
that's not an example that could be presented as tabs, because 
preventing people from navigating between tabs just by clicking on them 
is verboten.

Conversely, you could present the game board and the high scores page 
as tabs, but they're not intrinsically mutually exclusive, because you 
could present them another way that allowed them to be visible 
simultaneously (as Minesweeper does, for example).

In other words, Fantasai's right. That two things are shown in 
different tabs does not make them mutually exclusive; and  that two 
things are mutually exclusive makes tabs an inappropriate way to 
present them.

Assistant or "wizard" interfaces are more to do with dependency than 
mutual exclusivity. The existence of, and questions asked in, each page 
are highly dependent on what was entered in the previous pages. If 
that's not the case, you're just wasting people's time by making them 
flip through pages, and you should be using a dialog (with FIELDSETs, 
or tabs, or whatever) instead.
