That wasn't the case if you listen to the commentary tracks for Blade 1 & 2 with Goyer and Snipes. They both sounded like they had a good relationship from the interactions between the two. Goyer would actually praise Snipes on many occasions during the commentaries.
The method actor thing was never an issue on the first two movies either until Blade Tragedy came out and the movie didn't do well. So they had to throw Snipes under the bus for it with the ultimate blackball, while Goyer and Reynolds get unlimited chances even after multiple failures.
