I'm sorry, I haven't used this extension and don't want to mislead you. I may already have as I didn't realize this supports multiple trees, which might allow for using the "same left/right ids" in both trees because I assume there is also a "tree id", which might be the "root_id" in this case. If there was a unique tree id, I could see being able to have left/right ids that are common because they point at different trees. Again, I don't know and I'm sorry if I did mislead you here. I'm used to working with one tree at a time. I'm sure WW will chime in.
I use separate tables for separate trees as each tree deals with different types of hierarchical data.
