The Reference Desk/Re-entry of Skylab

From the initial edit of the page in 2010, the Skylab page claimed that the Doctor was involved with Skylab's construction, credited to Tooth and Claw. This is not true. At all. I've since fixed it; as the Tenth Doctor recounts that with his help, he brought it back to Earth in 1979. The way he recounts this to Rose at the beginning of Tooth and Claw strongly infers that it's before she enters the TARDIS with the Ninth Doctor.

However, the page also claims that the Tenth Doctor, with a non-recurring companion (so presumably post-Journey's End or at least post-Doomsday) "defeated the Zalphons" who had "used [Skylab] by [them] as a base" in 1979, the year it fell to Earth. This is credited to PROSE: Bennelong Point, from the Doctor Who Storybook 2010.

Now, I've not read Bennelong Point, but are these facts in opposition to one another, or was the Doctor just involved with two different things, with the direction of the debris and stopping whatever the Zalphons did having nothing to do with one another?
