This sounds more like a run. I haven’t seen Strava record or report GPS data for just steps taken throughout the day. But runs, walks, bike rides, and other sports will often record GPS.
But the op is right - if the ship is moving, the athlete will get “credit” for additional distance traveled, or they’ll lose distance, depending on which way they are running compared to the ship’s direction of travel, possibly balancing out if one of the other reverses direction at the appropriate time.

My point being that they may not be using it for the gps component, but other features like heart rate monitoring or meal tracking, etc.
