I haven't read the link, but common mode current follows the behavior of the feedline as an antenna, so common mode current distribution along the feedline will vary as with a piece of wire having the dielectric properties and dimensions of the feedline, and connected as the feedline is. In other words, that feedline is part of the antenna.
So the obvious question is, how many measurements along that feedline are you willing to make? :)
