ASICminer are going to have to increase their current hash rate by a large % to keep their current global hash % (this costs money, which in turn affect dividends).
ActiveMiner on the other hand, has chips/cases/PSUs paid for. So come August we will have already paid for and over compensated for the global hash rate increase and will be making more dividends than what were making the previous month.
If activeminer has payed some massive bills it is still affects the company finances today and those investments need to recouped from the later profits. Any normal company tries to postpone paying any bills as late as possible. There is no benefit of paying bills too early. Especially a company that is still desperately trying to raise capital it makes absolutely no sense to pay bills even a day earlier than absolutely necessary.
What has been the total profit of activeminer has made this year? Activeminer has a couple silly mining boxes but on the other hand it has made massive investments to chips/cases/PSUs which are still affecting the company since the investment has not yet been paid off by any profits made and the investments are still ongoing since there must be people working designing stuff and later running the production and setting up the shop is also going to cost money. The profits from the mining done today look totally ridiculous compared to the bleeding of money that activeminer has made and continues to make for these investments.
If you think that ASICMINER must follow some sensible accounting where the costs of operation affect the profit made and dividends are only payed out from profits made how it is that activeminer can pay out any dividends at all since the company cannot possibly be in the black any way you could possibly count it.
