The limit is 137GB.  Anything over that will have to conform to the 
ATA-6/48-LBA spec.

It is, in fact, not a mistake.

While many people report success with Power Mac G4 (QuickSilver 2002) 
systems, not all of them support HDs larger than 137GB on the internal 
ATA bus.  Only Power Mac G4 (Mirrored Drive Doors) and later have full 
support for every system shipped.  The document is accurate to reflect 
that.
