My guess would be that the video is taken from the first I-frame at or
before X and the audio from the first audio packet at or before X. The
I-frame could be well before X but the audio packet would be either
the current or previous packet.

Perhaps in smart mode the audio should be taken from close to the
I-frame too. Not really a bug, just a behaviour that could be quite
easily adjusted I would think, depending on what is deemed 'the right
way'. Else an option could be added to toggle the behaviour.
