While I am unsure how the actual number crunch this is likely what you are seeing.

This boss is Fire/Spirit vs Blackfrost (Spirit/Water). When behemoth attacks, it deals bonus damage to you because Fire beat Spirit. When you attack, you deal bonus damage because Water beats Fire. So while you are both hitting each other harder and you are also dying faster.

This boss is Fire/Spirit vs Rageborn (Water/Fire). When behemoth attacks, it has no advantage over you so it hits with normal damage. When you attack, you deal bonus damage once because Water beats Fire, and again because Fire beats Spirit. This makes you live longer and hit harder.
