Using Mike's method of Recording. A question

When one rotates the Toucam so that the image traverses across and parallel with the computer screen, as Mike suggests, what movement are we seeing - or correcting for? The Azimuth or the Elevation? And if it is one of either, then how is it that the image is not effected by the other?
I use Mike's method when recording AVI frames with reasonable success and assumed that if I could stop the Azmuth movement, then Mike's suggested method would contain the Elevation over 30 seconds.
Viewing the moon with an 11 mm eyepiece, the drive I've made, appears to stop the image with a very small downward drift, but using the Toucam it doesn't appear to make any difference with or without the drive.
The only thought that I can come up with is: either I haven't stopped the Azimuth, or I've under estimated the Elevation movement over the 30 seconds I had hoped for.
