Yeah, because age obviously determines how much I know...
I do know that yeah, the early demo recordings were a blend between more Hardcorish and Crust Punky riffs, but they had left that behind for a more Traditional Death Metal aspect when they began to get serious about it.
The only reason any post material would be considered grind in anyway is because of their early associations with Vinyl Solutions, and then after which going to Earache, who at the time were specializing in promoting bands in Napalm Death's and Carcass's deathgrind style, followed by featuring them on a compilation entitled "Grind Crusher". Of course, only a few bands on this were actually grind (Entombed, Carnage, Morbid Angel, and Godflesh are also on this comp). It took 2 CD's, but eventually everyone figured out that the band had left their grindish/hardcorish/crust aspects behind in the demos, and shouldn't be classified by label associations.
Edit: That all said still, I should reinterpret my initial post in this thread: "The only time I've heard them coined as grind in reference to anything but the demo material and label association, was this thread. It was heavily clarified early in their professional career, both by them and their music, that label associations mean nothing and they lay heavily in the classic death metal genre."
