Ever done it? I can't speak to any year other than a 2006 (okay, and 2007), but in a 2006, this does not produce the horrible grinding sound of the starter attempting to engage the spinning flywheel. Turning the key while the engine is running essentially just resets the Nav, stereo, display, etc. It does not interrupt anything associated with driving. I use this "feature" occasionally to reset the GROM if it's glitching.
I wish I could remember when I first did this... and why I knew it would not do what we'd expect it to do.
But the big question(s): Why does this feature exist? Or, did the Toyota engineers just put an idiot override in place, e.g. "if engine running then..." in the ECU firmware?
