They don’t cross, they both lay side by side behind the neck.
When I prepare for a dive, I first attach the left tank and route the left hose. Then I attach the right tank and route the right hose. The left hose is between my suit and the right hose. I call that crossing.
If I donate the left reg the free hose length is not much more than with the short hose.
After the OOA diver is calmed you can either sort the regs or switch between short and long hose. Seems for me not much difference.
