This is the tallest pyramid of glasses I have ever seen - when the camera pans down, it just keeps panning and panning... it's amazing. Watch as the guy puts the very last glass on top... will he make it? I was nervous for him.

While it IS possible to perform a pan while the camera is in motion, that isn't the case in this shot (sometimes, as in Hitchcock's Rear Window, zooms and tracking shots are combined to create a radical shift in the depth of field of a shot).
The beginning of the shot is a "zoom," in which the optics create the illusion of pulling back, not to be confused with a "tracking" shot, in which the camera actually does physically pull back, push forward, or travel sideways (usually on dolly track).
