If you go frame by frame starting from the point the ball leaves the hand, it looks within 30 degrees of vertical. Mentally breaking the 90 degree square using table as bottom base into thirds from where he tossed to the ball's apex it appears to fall within the first third starting from vertical. Although I will say the camera angle is not the best to determine verticality.
I was able to match up the two screen shots I took by matching the different colour panels on the wall:
The moving (blurred) hand is about to release the ball. His hand moves in a slight arc, but I think it's fair to say that this toss is probably closer to 30 degrees than 60 (its nowhere near 45, let alone 60).
But his example demonstrates a few points...
1) It's not explicitly stated where in the toss the 30 degree rule applies. The only interpretation that makes sense to me is that it refers to the angle as the ball leaves you hand (at the peak of the toss it is moving purely laterally).
2) There are factors that can make the determination of the angle quite difficult. Human nature is that if it moves a larger distance laterally, you're more likely to conclude that the 30 degree rule has been broken... but for a given angle, the higher you toss the ball, the further the ball is going to travel laterally.
Note also that at ~1min 30 into the video Anders states that "Let's say you throw the ball one metre up, it can maximum go 30cm to the side". Maybe someone would like to do the math, but that doesn't seem right to me. Also, does he mean the horizontal distance from leaving the hand to returning to the same height? From where his hand is at rest to where he hits the ball?
As a player,
1) Unless a player is throwing the ball into their bat, I don't really care about what angle the ball is tossed at.
2) I do care if the ball is being obscured in the toss
3) I care if the ball is not being tossed high enough
only if the server is gaining advantage from this. If I'm umpiring I usually let it go if no advantage is apparent. If the player is intentionally trying to 'pull a swifty' it is usually pretty obvious and I would call it.
