I believe this is just a trivial bug, and, luckily, I don't think it would actually affect anything. This could matter if an expanded iter domain got merged with a non-broadcast iter domain as part of a reshape op, but reshape converts expanded iter domains to non-broadcast iter domains, so this bug won't matter.
In the case of normal scheduling, whether the output of a merge with an expanded broadcast is still a broadcast or not shouldn't matter, I believe.
