I read all about it here but am confused slightly

I have a WD2500JB-00GVC0
This site says the DCM doesn't matter, at all. But there is a little code on the underside which is quite long.
Mine is: 2061-701265-200 AH --- XC 1X47 4PZ3 5 0001070 --- 6071
The part I'm confused about is that the website says "(2061-701267-200 AK). It is a “MUST” that you match the 2 letters following this number set or you will not have success with a simple PCB swap." Are they saying the 2 letters after just the number? or the 2 letters that appear after the code they've put. In my number, would they be referring to the "AH" or the "XC" being the extremely important letters?
