I came across the wikipedia article for barrelene claiming that has mobius aromaticity

but...
(1) Mobius aromatic systems have 4n delocalized systems and barallene has 4n+2 electrons
(2) What is the path of the electrons? I don't see how all 6 p-orbitals of the same phase can overlap. In other mobius systems there is a twisting and it's easy to see where the electrons cross sides.
