Yes, that is on purpose. The magic bytes of 0x4489 are a sync
mark, the interesting stuff always starts afterwards. The whole
decoding routing uses the current pointer the way that it always
points to the next unprocessed position when it arrives at the
next segment of decoding. I'd rather have this consistent in the
whole driver.
