There are more potential users and groups than that, but you are 
correct, you do not actually need that number, it was based on this:

Unix uses 0-999 for system users & groups (yes I know redhat used to use 
0-499, but they now use 0-999)
ADUC starts Unix IDs at 10000

If you use a range for the builtin users & groups above the domain 
range, it could get in the way if your AD domain grows enough, so why 
not put it below the AD range?
If this is done, where to put it? You will probably require some Unix 
users, so they will start at 1000, hence for ease, 2000 was chosen as 
the start ID for the builtin range and as it could only go upto 9999, 
this was chosen as the end number.
