As we've concluded here many times in the past, rockets don't care how fast they're going with respect for the surroundings. More energy or more Isp per given mass ratio = better performance as per the rocket equation. It does matter a lot with air breathing propulsion, but not with rockets or for that matter the technology of current discussion.
I think maybe it does matter with this technology - if it doesn't then it would be a perpetual motion machine, and even less likely to work.
