They are not spotting, they just threw her up there.
Yeah that ridge is tall but most would not consider it highball. Perhaps they are not planning on catching her if she falls though, merely guiding her onto the mat, but hey what I do know about such things.
I think what Mr. Shultz was trying to point out was that the spotters were risking injury. Experience has taught me that no spot can be and often is safer.
Fairly tall (12-18 feet), vertical (give or take a little), and a level landing can be best spotted away from the pad only helping a falling climber if he/she is flying off the pad into other obstacles (trees and rocks etc.). Allow the pad to do its job.
Of course every climb is different and a more direct spot might be beneficial (climber is going to fall sideways or fly outwards). If this is the case and the height is substantial than I recommend more pads or waiting until the difficulty of the problem is well within ones ability.
I learned my lesson the hard way by catching an elbow in the face suffering a broken nose and a mild concussion. The person I was spotting landed on the pad as we had predicted and was unscathed.
