DWM 38, dedicated to the episode, does not reference it being the second part of a two part story but instead considers it the first episode in the second part of the series. It also states that the episode concludes the cliffhanger from the previous episode, which seems to be the main confusion in my eyes. This pretty much seems to be that a reader of the magazine likely misinterpreted that statement and added it to the pages. But by that logic, The Parting of the Ways and The Christmas Invasion are also a two parters.
