This is the second least significant bit in the first byte. In your example, you are using an address that indicates its is globally unique with an OUI that has been assigned to Xerox (i.e., only Xerox should be allowed to assign that MAC address). If you were to modify the address to 02:00:00:00:00:01, then you are not stomping on someone else's legitimate use of a paid commodity (the OUI), and you also signify that the address is not globally unique.
