A heated gutter around the perimeter with heated drainage duct would be needed for egress. If they just heat the perimeter and let water drip off the roof, it'll immediately form ice piles below.

Maybe they don't care or there is no ordinance and therefore Apple's architect and builder doesn't care either. It may be entirely intentional and by design.
