Those words perhaps may be technically used as the way AZ does. However it is very confusing to us who are not so well versed in these intricacies of word usage, and think the words mean what they generally mean to the velt.
In addition, personally it makes me wonder if a person deliberately uses such important words and concepts in a way that is confusing and provocative, is there something else in his agenda which could possibly be somewhat misleading as well.
Those questions do not occur to me if an occasional Gadol occasionally uses such a word in an unusual way.
