‘Impossible’ black hole causes biggest collision ever detected by gravitational waves

At least one of the colliding black holes was in the ‘forbidden range’ and should not exist.

I don’t see any impossibility here.
If 66M and 85M black holes can combine to form a 142 M black hole, why can’t two sub-65M black holes combine to form an 85M black hole?
I didnt see anything impossible either.
Small black holes will combine to form larger ones that a single star cannot form.
