I think two different ideas are being discussed here. Drummereef’s explanation sounds (to me) like a mix between “cycling” a new tank, colonizing your dry rock to “live rock” and removing phosphates (PO4). Which, are all things you need to do. The other idea being discussed seems to be the concept of strictly removing the phosphates from the rock. Both of which are correct in their own regard, but it depends on how you want to go about it.
In my opinion, I want the PO4 out of the rock before I expose it to any conditions favorable for algae/bacterial growth (definitely don’t want to expose it to light). This is why I threw mine in a brute can with fresh mix of saltwater, a powerhead for circulation, NO heater and the lid on the can. Why saltwater and not RODI? I don’t know to be honest. If I were to do it again, I would just use RODI. From there, I did complete water changes every other week or so and pulled out and rinsed each rock individually (and the container). The first water change you will see that the water has a brown tint and a distinct smell (like muddy water?). I measured my P04 from start to finish but by the end the water should be clear and you will notice the smell is mostly gone (if you have a PO4 tester just create a log and test it every two weeks before you change the water). I don’t have my notes in front of me but I believe this took a little over 2 months.
Once the rock is free of PO4 you can put it in your tank but you will have to seed it with live rock from someone. I have always done this with my own live rock and I also added Instant Oceans BIO-Spira to help jump start the cycle (keep the lights off on the tank for another week or 2 to give the bacteria a little head start but all other systems can be online (skimmer/heater/etc.)). Whether the BIO-Spira actually helped anything? I have no idea. But I had read a lot of good things about that product and I figured adding a little extra nitrifying bacteria to get the system online faster couldn’t hurt. Overall I was pleased with the results of the live rock and BIO-Spira combo.
I think you will do fine with either method. I like Drummereef’s method for the fact it does everything at once. I just chose to break that process into separate steps to ensure my rock was free of PO4 before I started anything.
Good luck!
