Because you said when he first stood up, he was still talking to his friends, it doesn't sound like he stood up so that you could see him. It's not even clear that he had seen you yet. And it doesn't necessarily mean anything if your eyes met when he saw you because you were obviously looking at him. A few seconds isn't that long.
