Not so much being able to slow a bipe down, but once on the ground is when you need keep up the power allowing sufficient airflow across the elevator and rudder. At least that is what I have learned.

I can see where this may be helpful on a WW1 airplane where the gear is narrow and a little bit aft but on what I would call a " normal " bipe it really should not be any different then flying a mono. Landing fast is usually caused by having the CG too far forward.
