I pictured the screen approx 3-5 second after the driving time past 1 hour. I was prepared with my iPhone camera because I noticed that the values had unnormal difference after driving 58 minutes.

Interesting or not?
Not. The time period for the OBC measurement is different to the JC measurement, hence the difference.

The Owners Manual isn't overly detailed on this point:

Average fuel consumption
This is calculated for the period during which the
engine is running.
The average fuel consumption is calculated on
the basis of various distances.

So what's giving the discrepancy is likely the OBC and JC measuring different time periods, giving you the different result. Does this make sense or have I completely missed your point?
