Of course you can never fool a professional trumpet or clarinet player into thinking it's a real brass or wind instrument.

The point is that Mr. Baartman comes close. He can fool the average listener. The sound he plays is pleasing to the ear regardless of its authenticity. Furthermore, you can create cool string, wind, brass, and other sounds on a keyboard that you can't get on your native instrument - just like vice versa.

Yamaha's purpose in this video is to sell the T3 implying that you can do this too. Can a decent player do something close as far as sound emulation? The answer imo is yes. The S.A. 2 voices apparently have superior ability to articulate the ideosyncracies of the instrument it's portraying without having to keep your left hand constantly on the pitch bend and modulation wheel.

Very cool indeed.
