My best guess would be that the main conductors enter the panel through conduit at the bottom center of the panel, and then take that convoluted path to the top. That conduit looks like the only one large enough (?) to handle those wires - the one to the right is already crammed full. What the heck...who cares about wire fill anyway.
Never thought about using a cable clamp as a bug before...
This panel looks like the way I feel after eating dinner on Thanksgiving Day...STUFFED!
