You are correct that they are almost identical. As I recall, the 
difference is that the items in the 'add' list can be added by the user 
by right clicking on the node and adding them from the context menu. 
Whereas the 'move' items must already exist somewhere in the tree and 
can be moved to be children of the node. Of course 'add' items can also 
be 'moved', so they are a superset of 'move' items functionally.

Hope that helps...
