I don't know if he is a vegan or not, but I do think he is against animal suffering. I'm not sure what you mean by "he is right" unless you are referring to the first tweet (in which case I agree) because the second tweet is just kind of a weird ramble about eating baby clones and specific people's placenta.
Is he vegan? Because that tweet is very similar to that way of thinking and he's right.

He's right to point out that there is similar moral questions about killing beings to eat their flesh whether that meat is human or non-human.
Reframing it as "would you eat lab-cultured human meat" is a good way to frame it outside of the "killing humans is different than cows" mindset.
