Because |IBBP|I is better than |IBBB|I. (Where both are in display 
order, and | represents a scenecut.)

Furthermore, IPPPP is better than IBIBI in the high motion cases where you 
actually get IPPPP even with non-adaptive B-frames.

If you're really saying that you want complete control over the GOP 
structure even at a cost in compression efficiency, then disable scenecut 
detection too.
