That was me, Chet .... I use that method to remove the coils set in the line when the reel hasn't been used for awhile. And when you cut the line loose from the secured object, walk back to the reel and reel the line back thru the grass while applying moderate finger/thumb pressure to the line as it goes on the reel. That takes any twist out of the line and packs the line tight on your reel spool, which helps stop any loops or loose coils from getting overwrapped (another factor in kinked line and "birdnests" during a cast).
I've also used the free line dragged behind a boat at idle speed method to take twist out of the line. (NOTE : it don't take all that long of casting a light jig to impart quite a bit of twist to your line, reason being that the jig will sometimes spin when you cast it - especially if you use a wrist snap action when casting. )
