    The sources you quote are just quoting the most recent. This could of course
    be an error in identification of which satellite is which, or there was
    some minor manouvering at time of observation which the orbit model
    has amplified because it cant know that a correcting manouver was applied
    after the observation. We just have to wait till another elset is released,
    or eutelsat communicates its own observations.
