Soldat stops the ball from the pass with his foot, gives it a careful, experimental kick to gauge the strength of the rubber (or leather, or whatever this particular soccer ball is made out of), then repeats the drill Conan just made. They're not perfect, the ball escapes several times in the first few tries, but they're pretty good for one attempt. The repetition of the drill coming back is much cleaner, now that they know what it feels like.

Having excellent body understand, serum-enhanced learning skills, and a history of being pretty severely punished for failing at similar skills helps a lot with picking up things like this.
