None of the other blocks had matured, when we find the next block at least the first two will show up (and hopefully the third as it still has 22 confirms left). That's how Bitcoin works, doesn't matter if it's at this pool, another pool, or solo.
Ahhh, OK thank you! I hadn't realized that the other two hadn't matured before the most recent block was found. The pool's incredible luck this weekend gave me a weird situation for my first payouts! I appreciate the quick response, thanks.
Using normal luck, the next block we find will have three payments in it. It is nice though to have been involved, can't complain as that pays a month of hosting!
