Kind of – it is the behavior I already assumed and it enables my use case, but
I wouldn't call it intuitive.
Does this additional check only apply for `saddr . iif`, or also for other keys
like `saddr` alone?

That sounds good.
Adding a note to the wiki page [1] would be nice as well. I'd also do that
myself, but it seems like new accounts cannot be created.
