What you mean by " when the router sees a source" ?
If router creates pim (S,G) state withoyt output interfaces?
If router send (S,G) joint toward upstream router? 
If router send prune message in direction to RP?


I'm not 100% sure by ife we talk about "bridging PIM domain" probably we make general misteak. Let's assume R1-R2 link is a domains boundaty. To have things working in R1 (SM) domain you has to run PIM on R1 to R2 interface. Also on R2 (DM) you has to run PIM on interface toward R1. So SM and DM are only modes of the same PIM, so I guess they will establish neighberhood and effectivly form single domain...
