Not false claims, per se. Just a different way of measuring and/or stating on specs sheets. You wont get FUD from me (or Leica).

The 5D mkII (again from Canon USA):
Coverage -- Vertical/Horizontal approx. 98%98% linear is about 94-95% by area.
Here is Nikon's take on the D3x:
Viewfinder Frame Coverage -- Approx. 100%Again, "Approx." is used. No definition of measurement is given.
So, you can see that there really aren't any "true" 100% viewfinders on SLRs. This is not a jab against C/N, just a clarification of why Leica's spec for the S2 seems off. They (Leica) could have also used the same method of measurement and said that the S2 viewfinder is "approx. 100% coverage" as well.
