[Rules] [12.41] Assault Column Modifiers

[tlangston28]

One of the column modifiers for the assault table states that a defender gets a +1 column shift on the first assault turn if the hex is higher elevation. My question is - if the assaulting unit is in a hex with an elevation change and the assaulted hex is completely "on the hill", does this modifier apply or is the assaulting unit considered "on the hill" as well?
