My order just switched to 'Paied' as well - pretty much right after the 6th confirmation came in. Since they seem to be waiting for all 6 confirmations the 60 minute limit is indeed quite tight. So far I have not received a (payment) confirmation email either.

It looks like they have already received payments for quite a few more than 30 orders, closer to 60. Payments are immediately forwarded to this address:

I am wondering if the website is not enforcing the 30 unit limit, or if 30 or so of these payments are not considered to have been received in time (and will be refunded?).
