I've only seen a few Malinois, but there is quite a bit of variation in size and looks in the breed - they are not cookie-cutter identical like some breed of dogs. Plus you have the show line Malinois, bigger, bulkier, longer, plush coat, and the working-line Malinois, small and wiry and very short, close coat.
With my limited exposure to the breed, I'd say the first type is a typical working-line, the second type a typical show-line.
