If the camera has been demoed or used for QC then the setup would have been preformed and unless the camera was reset, those settings would remain in effect.

This count is also different from the image count which rolls over after 9999 the shutter count is a 32 bit unsigned integer and should be good for recording over 4,000,000 actuations.
