Can someone please help explain what the paragraph below means with regards to hitting low trajectory tee shots (esp those in bold)...

The neat thing is that the flatter ball flight is a matter of technique and not ball position or strength. The key to the shot: I break momentum on the follow-through by softening my arms and elbows to get extension of the club with my release (above). That leads to a lower ball flight. The club often recoils into an abbreviated finish. I don't try to muscle it. The more I soften my arms and relax into it, the easier the shot becomes.
