It's pretty simple. The position where biboo is, becomes the position where biboo wasn't, so it follows that the position where she was is now the position where she isn't.
In the event that the position where biboo is isn't my bed, the system has required a variation. The variation being the difference between where the biboo is and where she wasn't. If variation is considered a significant factor, it too, may be corrected by the pebble. However, the biboo must also know where she was.
