The problem with these theories is always that there is no real motivation for this kind of thing. TV producers care about ratings. It makes sense that they might want to protect certain acts in order to sustain interest in the series. But why on earth would they be bothered about which one of 13 acts went home in week one and then week two and week three? So long as their big names stay (and they're protected by the judges vote anyway) they wouldn't care.
The last act on should always bring the house down (true in the old system, true in the new one). A good act should always be on when there's a scheduling junction on BBC1 (end of Strictly or end of Merlin). There should always be a good act "coming up" - where there are two acts in one segment, one of those acts should be good. On a practical level, there are issues with staging (particularly where two acts perform back to back). They'll also try and mix it up between the categories (so one judge doesn't have several acts in a row) and types of songs (don't put 3 dreary ballads on in a row).
When I say "good" - I mean in the TV sense. An act that might be a draw for viewers. Either someone really talented or possibly someone controversial or someone that has had a particularly eventful week.
