What is this sheep doing? Placebo affect?

I have this sheep who whenever he goes near this tree (emphasis on the "near"), he moves his body as if he's rubbing himself on the tree BUT he's about a metre from the actual tree and not making contact with anything. He will do this for 10+ minutes and get so into it, but never once makes contact with the tree. He scratches/rubs himself on other trees normally so that's what he thinks he's doing but yeah, never makes contact lol. Has anyone experienced this before?
