The L5 moniker "safety of life" is an accurate name. It will assist GPS aircraft navigation, especially during the safety-critical landing approaches. Aircraft rely heavily on both GPS and WAAS satellites for corrections. Actually, L5 has been broadcasting on the two WAAS satellites for several years, but most end-users would not have used it. AFAIK, L5 decreases the error from multipathing and the ionsphere, among other improvements.
