Its interesting but I wouldn't say perfect. The sound samples are of the pedals played through an amp, right? So if you wanted to to a proper tone match of the pedal, You don't want to capture the amp tone.
What I would do if I wanted to tone match a drive pedal the axe doesn't have is start with their (say) TS808 pedal sample, and tone match it to the pedal of your choice. Then in the Axe-fx create a patch with a TS808 drive block and put the tone match next to it
