Unless they are hosting the servers in orbit your destination will be on earth somewhere. You will come back down go to it then return through a similar path to the client. the speed of light in a mostly vacuum could (provided their meshing algorithms are up to it) make latency comparable but MEO sats already have a 125ms rtt time halving that distance isn't going to get rid of that penalty.
