But how does that 50ms factor into the overall latency experienced by the end user?

As I recall, SpaceX will route user<->sat1<->sat2<->server. At low orbit, rtt for sat1<->sat2 is comparable to that for user<->server. Maybe even less, because ~vacuum vs fiber or copper. So you just add 50 msec to the landline rtt.
