Conceivably it could, if it doesn't know the difference.  And I suppose 
you could use firewalling and/or VLANs to ensure that the media that 
flows "out" from the proxy in both paths (relayed to the far-end 
destination) doesn't actually reach its destination and create a conflict.

RTP relay is a very dumb process;  there's no end-to-end acknowledgment 
or any other kind of backward notification, except for RTCP, which is 
basically just QoS reporting and will not change the state of the stream.
