I think he is doing the large changes to avoid any larger swings, if he leaves it the tank water will drop in ph more.
I suppose lots of 10% changes would help but if you make it a daily chore it might not get done
Large Water Changes Bad?

pH swings don't affect fish unless there is ammonium in the water which becomes ammonia because the pH rises. pH affecting fish is one of those old wives tales.

i believe this would be an opinion...
im all for very large waterchanges. i dont even use prime since we have very clean water water.
I believe it's a fact 
There was a good paper on the subject but, naturally, I've long since lost the link for it.
But from my own experience back when I had discus breeding.. I used to use reconstituted RO and fiddle with the pH in a 29 gallon tank the discus were in. I ran a digital continuous pH monitor so I had a very accurate reading of the pH which would update within seconds of a change. Anyway, one morning before work I decided I'd drop the pH a bit because I figured they were about ready to spawn. I upended the 'pH down' bottle, incorrectly 'remembering' that that bottle had a dropper. WRONG, it was an open top bottle - so instead of a few drops a major glug went into the tank and the pH immediately dropped like a stone. The discus didn't react in any way whatsoever, I re-upped the pH and they spawned a few days later.
General hardness yes. pH no.
My water has chloramine so dechlor is not optional for me.
