okay, I have a simple way to describe it.

Your image on a 10 bit scanner has a range from A to B, but the scanner 
can capture from A to C (ABD).  On a 14bit scanner, it would still be A 
to b, but the scanners range would be increased to ABCD. All of this 
would be on a section of the 16bit range which would be ABCDE. 

This is why a 14bit scanner does not capture more information than a 
10bit scanner as long as the negative is within it's drange 
capabilities.

Again, I am not sure if this is true, this is just what Austin was 
saying "because of how scanners are designed"
