James seems to be stretching his interpretation a bit far.

Agreed that, while the voter can choose to rank all candidates, the voter 
is permitted to omit those least desired.

In Condorcet every ballot is counted.  For each the counter considers EVERY 
pair of candidates, such as A and B.  If the voter has indicated preferring 
A>B, that is recorded toward A winning; likewise for B>A.

As to IRV, while using the same ballot, it only looks at enough to satisfy 
it purpose - which DOES NOT INCLUDE knowing whether the voters like A 
better than B.
