I made a video demonstrating the different warp settings and the fact that repitch doesn't always cancel. It's a little boring and maybe a bit confusing but I can explain what's going on step by step if anyone cares.

in digital audio all you have to do to change the pitch or speed of something without timestretching is keep the playback sample rate constant and increase or decrease the sample rate of the sample - so in repitch mode the only thing that will affect the quality is whether Hi-Quality interpolation is on or off
I think maybe what's happening regarding warping is slight variations in the warp on the sample - such as a sample that was recorded at 120bpm showing up as 120.04 bpm or whatever, then you are bound to get phasing issues
the sample is being constantly manipulated to keep in time with the project tempo, so if Live doesnt have to do anything to it then it should be left alone, but if it thinks there is any variation at all between the sample tempo and the project tempo then it will adjust it, which is where i think the phasing is happening
although I have definitely noticed in complex mode before if something is at the same tempo there was phasing, but I mentioned it and think it was some kind of bug - I havent tried it again since Live 6
