Historically, the mean motion of the ~250 x 1000 km KeyHole orbit has been maintained between approximately 14.74 rev/d and 14.81 rev/d. Nico's last pre-manoeuvre and first post-manoeuvre elements, shown below, conform to this pattern. That leads me to believe that the primary purpose of the manoeuvre was routine orbit maintenance.
