What I recall zefir saying is he plans to order more as long as more orders come in up until the cut-off date May 1st. If a partial batch is left unfilled then he'll return funds.

But if everyone waits for others to order and doesn't pay theirs then he won't know that another batch can be done. I don't believe he's interested in keep tallies of everyone's maybe, possibly positions. He's going to watch when the address balance reaches the right value and then order. If no one commits, no order happens.
