Short steps feel faster because your limbs are moving faster. It doesn't however permit efficient impulse generation to accelerate in the best way possible. As D3 hinted, the initial pushes should be powerful and complete (rather than short and choppy) and progress to shorter ground contacts as the athlete approaches top end speed.
How would this compare though with something that appears to be seen in many elites: their best starts have shorter, faster steps. In any of Ben Johnson's races, you can see this. In 2004 Olympics, Gatlin had probably his best start (and best race for that matter) and it appears to me that his steps were not quite as exaggerated. In Patrick Johnson's sub 10 run, he also had relatively short, but fast steps out of the blocks. Even Maurice Greene appears to have slightly shorter, but faster strides out of the start in his best races. Maybe I am just going crazy though and this is all crap, but it's just what I have seen.

Elite sprinters are taking full, complete strides, just at a much higher rate than most people. The tendency for most novices is to cut their strides short and rise up too quickly.
