Wikipedia is listing the episodes from Smash the Mirror onwards by both their Production Code AND the Official Airing Order by which they will appear on the DVDs and by which they appear on the official ABC website. Smash the Mirror is listed as comprising Episodes 8 and 9 (as AIRED) AND Episodes 408A and 408B (as PRODUCED), as are the subsequent episodes Fall, Shattered Sight, and Heroes and Villains (and as will all subsequent episodes thereafter). The Production Codes do not appear on the Wiki's main Season 4 article page, but they do appear on the individual pages for each specific episode.

I know that this is the case because I was personally responsible for ensuring that it happened because it reflects the most accurate way in which to document the season as it is comprised.

Production Code is not always the most accurate way to chronicle the order in which a season is to be viewed IN AND OF ITSELF, and is often trumped by decisions that are made after-the-fact. In the case of Smash the Mirror, ABC recognized that the two parts of that story were shot under a single two-part Production Code, but chose to accurately relabel them for distribution as comprising Episodes 8 and 9 of the season.

The Wikipedia articles on the season recognize this and have presented things accordingly as recommended by me and agreed upon by a number of other prolific contributors to the site, and it is my suggestion that this site follow suit.
