An allistic person is usually thinking “How can I get what I want without conflict?” (Unless they’re unhealthy and think of how they can win upcoming conflict.) and while autistics want the same thing, they usually do not notice or predict areas of conflict.
Notice how in the second video the guy is basically subconsciously thinking to himself “I don’t want to date a fat woman and I don’t want her to know that’s reason because if she knows there will be conflict and she will feel bad therefore I will hide this analysis.” Hugging her was a very sneaky way of checking for her body weight. I’m not saying he is wrong for wanting what he wants but he is hiding it.
But in the first video the autistic guy is more direct. He wants to share the same admiration for natural environments. Simple. However he put in zero effort in hiding his rejection.
This is why I believe allistics are more guile. Sure it creates social harmony but you need a deceptive brain to think about how to accomplish that.
