Information regarding the last_updated line seems to be on the last_changed line. This was somewhat confusing at first, as it suggests that last_changed might change under the same conditions as last_updated.

The line for last_changed states:

last_changed: timestamp last time the state has changed. A state_changed event can happen when just attributes change.

This is followed by the line for last_updated:

last_updated: timestamp anything has changed (state, attributes)

It seems that the second sentence on the last_changed probably belongs on the last_updated line.
