The use of the qualifier 'active' is a real problem. The definition of what is a links section and what is not, should not change it up on the status of the device specified in the state diagram. The links section is the links section is the links section at all stages of the state diagram. If we use the word Active in the definition, then somewhere in the middle of the state diagram the piece of cable becomes the links section. That's just weird and wrong.

This all has me wondering what active means...
Does active mean both PSEs are powered but only one is "active". Note Dual-sig PDs will present a detection signature on both modes.
Or does active mean powered?
The word active can be deliberately manipulated to mean whatever a vendor wants it to mean.
(GOT) I was under the impression that 802.3bt allows you to gang one active endspan PSE (Alt A) plus one active midspan PSE (Alt B) simultaneously to get additional power.
^^^ this is a really bad idea, the IEEE should have nothing to do this type of system
