That is a logical fallacy.Class abilities can have effects. Example: Lay on hands.
All A have the trait X.
All A have the trait Y.
B has the trait X.
Based on this information only, we cannot logically conclude that B has any other traits than X.
In our actual game text world, it is even simpler because any A or B only has the traits that a block of rules text specifically gives them.
In the case of BA and EC, trait Y is whether it is a effect.
