You can't easily tell whether someone has Asperger's or not from a random snapshot like this.

Autism spectrum is, as the name suggests, a continuum of the severity of autistic traits. Among other things, autism affects how sensations are processed by the brain. Normally, a vast majority our sensations are heavily abstracted or filtered out by the brain so as to enable us to focus that which is relevant. An autistic person has broken filters in the sense that some perceptions are blown completely out of proportion in their minds commanding an intense focus. For example, a tag in the back of a shirt or a seam can feel so disturbing that a child can be totally unwilling to wear certain types of clothing. A normal child would adjust to such things quickly. Autists are great sticklers to routine because routine helps them organize their chaotic experience of the world.

Not only is sensory information processed abnormally by the brains of autists but some of their internal mental states, too. Many people on the autism spectrum have difficulty mentally processing their own emotions and, consequently, the emotions of others and social cues. Their theory of mind concerning themselves and others is typically lagging behind age appropriate levels in children and youth. An autistic child can, for example, burst into powerful anger over something trivial and it can take a long time for that child to calm down.

Asperger's syndrome is a relatively mild form of autism. In addition to Miro who will probably receive a diagnosis, I've known at least four people with a diagnosis. All of them are adults. Each one of them is an individual like anyone else but what's in common with them all is sort of living in a tunnel mentally as @gamer00 aptly put it.
