TAG soft on chipping, it seems

I was contemplating buying a card off eBay that was TAG graded, just to look at the slabs in hand.

I have issues with the corners on this card. With that level of chipping, there’s zero chance of that card getting a PSA10 or even a CGC 9.5. Given TAG claims to use absolute values, how is something as apparent as corner chipping treated so softly?
