good question... I guess I assumed it would only get air in it if the valve was vented into it either by overpressure, or by pulling the dump valve cord

If the smb can deploy, even partially, and gets tangled on part of a wreck, you'd have to figure out how to cut off the smb, and your bc would presumably then have an opening if you cut off the smb. Now if the BC has to be fully inflated for the smb to deploy, this would be less of a possibility.
