> It definitely has 'charm.' That's actually a good example of what the author is (probably) talking about. The link you gave takes Bach's originally 3/4 setting of the melody and "decompresses" it by stretching it to fit in 4/4 time. The cover version multiplies the duration of the first note of each measure by two. That gives the melody a more lyrical, singing quality. Also, the imitative countermelody of the bass is removed and replaced with a more regular guitar accompaniment. Hence, charm. :)
