Is it normal to think my brother's a vegetarian?

I can see his happiness and pride from his eating a large pile of vegetables, he calls himself a flexitarian and he eats a lot of vegetables, he's not fooling me with his occasional meat-eating, he's a vegetarian and he does it with great pride! He smiles so happily when he eats a pile of fresh vegetables from his dad's garden, on a plate, I've seen how he's enjoying this. I'm about as vegetarian as he is. When he fails to realise I'm in the room he's as proud and happy as he can be, do you think he wants to eat meat? He's only keeping my dad happy, he loves vegetables, and I think he thinks it's healthy. Is that normal?
