It's been reported that the picture was taken at 1988, so it's hard to say what Cerny was doing there at the time. This is right after Missile Defense 3-D for the Master System the year prior, and well before before he'd be involved in Sonic 2. Perhaps some other project in-between that only diehard fans are aware of? There's the possibility of the Moonwalker arcade and console games of course.
Though one thing is known; the first comment in the IC post asks: "Is that a young Macaulay Culkin in the sunglasses behind him?" Nope; they became b-fries after Culkin's breakout performance in Home Alone, which came out in 1990.
