Yes these tunnels are default MDTs and if you are using PIM SM or SSM in the core each PE will be root of its source-tree and member of source-tree of all other PEs.
But if you will use PIM BIDIR in your core (if supported), then I think there should be only one bidir-tree which all PEs can use to TX as well as RX messages.
