What we used to call "Famous last words." The problem is not confined to grease getting behind the springs. I used to see a few broken freewheels each winter in New England, always as a consequence of the bike owner filling the freewheel with grease. If the spring in your freehub is robust enough to force the pawl through the grease such that it engages fully, great. If not, a pawl failure can be quite a surprise when it happens.
