Slab Says BGS 8.5, Advertised As Bumped To BGS 9?!

Up for auction is a 1994 SP Alex Rodriguez BGS 8.5 which the seller states has been bumped to a BGS 9 as advertised by the "red sticker" on the back of the card. So if I read this correctly, if I win this auction, all I have to do is submit the card to BGS and they'll bump the 8.0 Corners to a 8.5 Corners; thereby raising the overall grade to BGS 9? Has anyone ever seen this before? Images are below.

I had three cards I was selling on consignment for a friend that were graded PSA 9's, reviewed by BGS.... then put into sleeves with the red tape seals just like the A-Rod shown above.
Looks legit to me.
Also, I wouldn't call the seller lazy. Sometimes it's not worth sending in one card for the bump considering it would cost over $25 to get it slabbed in a new holder, with the two way shipping costs, insurance, and grading fees involved.
