I only read the first page, but frankly, if it's not the horse for you, it's not the horse. And in the US, unless it's in writing, it didn't happen. Sellers know that (or at least they should and so should everyone else in every "agreement" they make), so if they held the horse, they did so at their own risk without a written contract. Whenever I make a verbal contract for selling something, I tell other interested parties that there is a "pending" offer, but if it falls through, oh well. I didn't have anything in writing so nothing is guaranteed. And then I call the other interested people.
