Status report question

What does the Addressed Units row mean?

[X10 Pro]

It basically means the unit has been controlled recently. This will mainly tell you what modules will respond if a dim command is sent on that House Code.

What you usually think of as an "On" command is actually made up of two parts -- the address, and the command. So, when AHP turns A1 on, what gets sent on the powerline is A1, and then A On. You can send multiple addresses followed by the command: A1, A2, A4, A On. This will turn all 3 modules on, and will leave them all in the "Addressed" state as tracked by the interface.

Should I assume it's the Addressed Unit of the Monitored House Code then?

[X10 Pro]

Yes. All of the interface status information refers to the Monitored House Code unless it's labeled otherwise.
