From 55.3

" If the unit would overlap no more than a single tray of an allied unit during a move and does not overlap any part of that allied unit at the end of the move, that allied unit is not treated as an obstacle and does not cause a collision. To complete this movement, the unit may need to be picked up and moved over the allied unit."

Is this read as you could pass over multiple allied units as long as it is not more than one tray of each of those allied units?
