Correct.

For atleast AAL5, bidirectional point-to-multipoint connection is not
supported because there is no such "multiplexing identifier" (as in AAL 3/4)
in cells, so that root can distinguish cells from the different leaves. 
Packet reassambly is only done by AAL layer (not higher layer) and 
implemented in hardware usually.

I think that is the reason why the connection is supported.
