"The difference is one of biology. The sensory input I received was different, as were my physical needs and responses. My mind, however, seemed... analagous, allowing for the differences in a positronic brain and an organic one. There were differences, but I was myself."

And that's at the heart of everything: that the differences between him and a real human are far more delicate and insignificant than he'd realised. There are differences, to be sure, and some seem very insurmountable, but... the mind is the same. And it's strange for him now to be able to remember a time when he wasn't bound by the Laws at all, when he was completely human rather than a close analogue, but whatever arrangement of positronic relays that makes him uniquely himself carried over.
