Whilst this policy isn't definitive, and does support the classification of occasional three-part stories which have been stated by the writer not to be so, it is a less controversial starting point for TARDIS policy than what we have at the moment. There is precedent for non-consecutive weeks being a two-parter, but that was only a two-week gap between The Sontaran Stratagem and The Poison Sky, and the gap was not a deliberate production decision.

What there is not precedent for is a story sharing no elements with a traditional two-parter to be called a two-parter. Both A Good Man Goes to War and Let's Kill Hitler had previously-on segments, but unlike the traditional two-parters of the era, the previously recapped the entirety of Series 6 rather than the previous episode.

As a sidenote, Utopia had its next-time trailer after the credits similar to other two-parters, so it can be inferred that it is Part 1 of 3. Utopia is a special case because it's a multi-parter - Captain Jack Harkness/End of Days/Utopia/The Sound of Drums/Last of Time Lords/Time Crash/Voyage of the Damned. In my book, that's a seven-parter.
