I thought SAS/SATA drives were point-to-point wired?

 My understanding is that the SAS / SATA physical /link/ is point-to-point.  That's why SAS and where SAS /exapnders/ come into play.  They multiplex the multiple logical & physical connections onto one physical.
 

I.e., can you hang two drives on a single cable without any extra electronics?

 No.  My understanding is that the extra electronics are required.

This was the source of my query:
    "It seems as if the ones that hold fewer drives might simply be pass
     through while the ones that hold more drives probably have expanders
     in them."
