I don't think UA is anticipating such a massive delay that will give the 747s a stay of execution, though that would certainly be a silver lining.
But they are still only receiving 14 77Ws and losing 20 747s. The 77Ws also seem to be headed for routes flown currently by 772s along with 747s (see EWR-TLV). So, the math doesn't add up.
What I am surprised about is UA acquiring used 77Ws instead of purchasing new ones. Boeing is giving such massive discounts right now.
