Boffin Contradiction

...The object has used no propulsion during the time NASA has had it under observation. However the spacewatch boffins believe that it must have moved under its own power at some point, given its position and velocity.

...The experts believe that the object must be a spacecraft, or more accurately part of one - sadly not an alien visitor, though. Rather it's likely to be a booster stage from an interplanetary mission of the past, now drifting back in to Earth and out again.

How can it be both a part of a spacecraft and yet somehow moved until it's own power ?
