Again, not a great equivalent to what he said.

If you mean creationism to mean Christian doctrine then you do not get the mass nullification effect. If you mean creationism to mean all creation myths then of course you do. However, as soon as you add evolution it changes things because there is evidence for evolution and it “is predictive” and therefore testable. That means that you are not relying only on the existence of incompatible alternatives for nullification. This breaks his premise.

It is not a particularly great statement. But all the alternatives here in the comments seem to miss what he was saying.

The “logic” of his statement is that there are many incompatible religious options presented. The incompatibilities mean that they cannot all be right. The number of options serves as the “evidence” for wrongness. Without independent evidence to support any given option, the weight of evidence against it ( the combined likelihood of the other options ) is greater than the evidence for it it ( single option ). You could make the argument for each alternative individually until all have been eliminated.

You cannot do this if evolution is an option. It has more evidentiary weight than the aggregate evidence of the alternatives. Evidence wise, it is logical to take evolution as valid and reject the others. Remove evolution and the remaining portfolio of creation myths is left with no clear winner ( and hence the likelihood that they are all losers becomes logical ).
