Well that boundary is the magic positive versus negative signed 64  
bit integer value.
It's really just a cross check to confirm everything works as  
expected in the 64bit version.

it would appear that you've done below that value, and above the  
value with your 0xFF testing,
it's just the crossing of that value, to dot our I's and cross our  
t's so to speak.
