I assumed from your statement "The man poured enough water onto the plate to cover it." that it meant the water "completely" covered it - which the only way that could be possible is if it went to the very top. If it did, you could not put the glass upside down on it without spilling it.

Even if you tilted it slightly, you could never displace the exact abount of air as water. And, besides, the mass of the portion of the glass submerged would displace the water as well.
