OK, I have a micro 4/3s rig with single strobe (Oly EPL-1 with Oly Housing and Inon D2000 strobe) and use a BP/W with a 7 foot hose and a Salvo canlight. My camera unit is slightly negative (my preference) and is hooked to my left chest D-ring using a coiled line system. I've had no problems with doing Giant Strides, back rolls, etc. AND I've also had the system lowered to me.
I have also scootered with this system and when doing that, add a second clip which goes to my crotch strap.
BUT IF you really want to have it clipped to both chest D-rings (I'm assuming this is for travel and NOT while you are shooting), there isn't any reason it would have to trap the long hose.
A. Just lift up the hose and run the strap underneath and clip off;
B. If that is too cumbersome, switch to backup (assuming under your chin), take long hose off, clip system to right D-Ring and then re-route long hose.
Either way, the long hose is now OVER the camera system.
I wouldn't do it that way myself but, instead, if I needed/wanted a two point system, clip to left chest D-ring and crotch D-ring.
