DavidSW Regrouping Grand Seiko Question

[WS9D]

I'm curious, purely for discussion as we will probably never will know unless David answers himself...

Up until a few months ago, DavidSW had Grand Seiko listed as it's own brand on his listings. He has since consolidated it to just a Seiko grouping which is all encompassing of GS and Seiko. I wonder why? I feel like it will make it harder for those new to the watch game to find pre-loved GS on his site. I wonder if it's intentional as not to take away from Rolex Sales since GS is so awesome? People will just assume it's a Seiko? But that doesn't make sense either as I know he wants to move inventory rather than have it sit.

Just curious what you guys think. I realize this has zero impact on life.
