It wouldn't be equivalent to our memory model, because it would kill
forbidden executions. Specifically, each forbidden execution has a read r
that is forbidden (more or less); there must be an alternate, legal
execution with the same prefix of r where that read must see another
write. If the read has to see the last write, you can't see an another
write.
That may just have pushed your question around a little. Feel free to
follow up :)
