Does your x260 create the same topology? Yes, that's by design. Now every start point for a device must be a port (either narrow or wide). The port-0:0:X are ports formed on the expander. And, since you only have narrow devices attached, that's all it shows you'll see this if you look at the tree under /sys/devices rather than /sys/class (since the latter is flat). All of the port-0:0:x will show up under expander-0:0 (just do ls /sys/class/sas_expander/expander-0:0/device/ to see this).
