This is an old phrase that has become condesed and reversed in the original meaning. Originally to be in a tree was to be stuck somewhere mentally, emotionally or situationally that you could not easily escape from on your own. The proverbial cat stuck in a tree that the proverbial fireman needs to rescue. Of course, cats are perfectly capable of getting out of trees, which is why we do not see many cat skeletons in trees.

Proverbially, they are stuck in a tree and need someone to talk them down, out of their tree.
