I am not going to say anything other than having been with and around reptiles for 25+ years and having constantly kept them for the last 10 years, I think there is a lot about reptiles people don't know, especially captive bred reptiles. Comparing the instinctual behaviour of wild reptiles with that of captive raised/bred ones is not going to prove anything as every thing acts differently in captivity. Take rats for example, rats in the wild run from humans where as in captivity they became very close to there owners and often prefer one person over another, they become depressed if they are ignored for a while and excited when they haven't seen someone for a while (this is pet rats, not food rats). They play with you, curl up and sleep with you, roll over to get their tummies rubbed. Is this all instinctual behaviour, I doubt it. I'll give one reptilian example, I had a blue tongue that actively looked for my dogs when he was out. We could all be sitting an the rug in the lounge room but he would make a beeline for the dogs and get comfy with them. They were obviously, from an instinctual point of view as big if not a bigger threat than us, they never fed him etc, so why out of a room full of people, dogs and cats, did he choose the dogs to sit with?
