They have admitted that they said two contradicting things. They said the 1st of July but they also said 90 days and as you can see in your pic the process started 11th April.
Although annoying I know i would be pretty pissed off if i had only found out on the 4th July what had happened at Instawallet and wanted to claim my funds back, only couldn't because it had all been re-distributed.
Personally, I think it was the only thing they could do in the circumstances.
5 days and counting now anyway.

I took that picture today. Anyone with funds at Instawallet who didn't come here to find out that info would not have any way of knowing that the information currently on display is wrong! It's not like they've had nearly three full months to fix that...
Also, not to split hairs, but 2013-04-11 + 90 days is 2013-07-10, not 2013-07-11:
mysql> SELECT (DATE_ADD('2013-04-11', INTERVAL 90 DAY));
+-------------------------------------------+
| (DATE_ADD('2013-04-11', INTERVAL 90 DAY)) |
+-------------------------------------------+
| 2013-07-10 |
+-------------------------------------------+
