  Perhaps on the compiler and OS and machine you are using, they happen
to be the same.  On a compiler I regularly use that is targeted at
Intel chips, 'access is 32 bits (assume a single segment, ie flat
memory model), but System.Address is 48 bits (segment + offset,
necessary in some situations) Clearly you can't use
Unchecked_Conversion there, and the compiler's
System.Address_To_Access_Conversions takes account of the difference.

  Just making an unjustified assumption. ;)
