This is actually a very good idea. What this fixes is the infamous G and B string going out of tune. I saw some youtuber describing how when he strings a Les Paul, he lets the G,B,E strings move UP the post instead of down. This way they end up a bit higher, reducing friction on the nut, this solves a lot of binding problems that get the strings out of tune. Ever since i saw this I've been doing too with very good results.
