The inversions on both inputs to the NAND gates bothers me. Wouldn't inverting both inputs as well a the output turn a NAND back into an AND gate?

A NAND gate with two inverted inputs is equivalent to an OR gate. The ouput is only false when both inputs are false.

You're right, it doesn't seem like it should but that checks out:
