Right here is where the crux lies. An up or down vote on two entirely separate pieces of legislation. Don't see a problem there? The slaughter rule introduces the problem that the house and senate passed legislation with different texts. The Senate passed their bill and the House passed the Senate/Reconciliation Bills. You can't combine the bills and then separate them out for signature because the reconciliation bill is clearly amending the Senate Bill.
So then, the House sends up the Senate Bill saying it passed on vote, when the truth would be it passed along with this other bill amending it. Again, its combining it into one vote because they might not pass on their own, then separating them out for Presidential approval. But that means the Senate Bill never got its own vote. Please go read by post above from a WSJ piece from Michael McConnell. It lays out the possible legal issues with this approach.
