Badds has done this for years, even as an amatuer when he won his first Aussie open. Gotta go with what works for you though, no point forcing a routine that is not yours.
Similar to phils routine for short putts where he goes around the hole I guess?
Another good point is image retention. We all have different abilities to retain images in the mind's eye. Some can hold the image of a candle (whatever...) for only a split second, while others can hole it for a long time. So don't go against your natural image retention.
