Default Re: meaning of union of hypothesis sets

You get only hypotheses that were in one set or the other, but no added "combinations." It follows the formal definition of a union of sets (hypothesis sets or any other type of sets); the union being the set of all elements that appear in any of those sets (and nothing else).
Where everyone thinks alike, no one thinks very much
