Presumably, if you're reaching across the pad, you're looking at the monitor, and if you're touching something on the pad then you probably can't see through your arms/hands anyway.

That being said, I think a second screen would be preferable all the same, but it would probably bump the cost significantly.

Screens are [comparatively] cheap, esp. Vs a custom projector + touchpad + 3d camera set-up. I don't think they went this route to save on production costs.
