Is this a violation of the multi-boxing rule?

Just curious, as I don't want to end up on the wrong side of the rule here.

My son plays at the computer desk beside mine.

Let's say we're both medding near the zone line, and a train comes along while he's upstairs afk. If I were to zone my character out, and then get up, and go over to his desk, and move his character out, I guess technically that would be a violation of the rules, wouldn't it?
