When I was mountain biking, bikes were often equipped with quick-release seat post clamps. This allowed seat height changes for different parts of the ride. On a technical section, you might lower your saddle. Then you could raise it when riding a flat, straight section of a trail.

I guess some people feel they need easily variable seat heights on all of their rides--even their commutes. At least, that's what this rider seems to like:
