I don’t think that this is what the rule is saying. “Similar to Rowhouse bypass movement” suggests that there is an additional MF cost to be paid ie one MF to cross the U9/V9 vertex and two MF to enter the building. It would cost 4 MF to go in the opposite direction.Assuming no weather or such, just 2 FM
if ascending elevation, Infantry would spend 4 MF (two [2 × 1]
to “bypass” and two to enter the building).
That statement pertains to Rowhouses. In the depiction provided above the Ground level of the building in U9 and the 1st level of V9 are at the the same height and within the same building. Wayne is absolutely correct. As per B23.72, last sentence: "The first level of the higher hex connects directly to the second level of the lower hex. Movement within the building to the ground level of the higher hex must be made from Level 1 of the lower hex, etc." Therefore, as Wayne stated/intimated the Ground floor of U9 connects directly with the 1st level of V9.The second independent clause of the rowhouse example in B23.721 states what Doug says:
That wasn't the question though. The issue is the MF cost to move from the ground level of U9 (at level one) to the ground level of V9 (level 0).That statement pertains to Rowhouses.
