I think you are reading between the lines way too much when you try to 
explain how/why it works.

The right answer is because the documentation says so.  The firmware can 
easily do it either way.

Some NMEA devices are off by a second.  I assume that's because their 
software geeks didn't read the documentation and/or didn't understand it, or 
maybe just got it wrong and nobody noticed.
