My take on this is that there is no tree conflict on the target itself.

The user has asked Subversion to merge a set of changes into a target
in the working copy. The target happens to be locally added.
The changes being merged might not be ancestrally related to the target,
but that in itself is no reason for a tree conflict to occur.

Subversion should try its best to apply the changes to the merge target
as instructed. There can occur tree conflicts *inside* of the merge target
if it is a locally added directory. But the target itself is just the root
of the tree the merge operation is applying changes to.
