MOV R1, #22H ; set R1 to point at DATA address 22H
Now I'm truly a noob here, but doesn't this actually mean: set R1 to the value 22H (0x22H)? both the document and you are right: MOV R1, #22H ; set R1 to the value 22H so that if it is used as a pointer ( mov a,@r1) it point at DATA address 22H; Likewise, if it is used for external data it will contain (be part of the pointer to) the lower byte of the address.
