The description of Jos is sufficient to understand how to intuit their function.
You have to merge the two planets to understand it. In addition to what jos said, this can lead to being skilled manipulators, having a lot of power regarding speech/communication, strong charisma. Propensity to speak or address, make friends, know people in positions of power, or who have power in some way, such as rich people, more influential people in one's city etc....
In some cases there is a lot of tendency to obsess very easily, because Pluto tends to dig deep and not be superficial.
Madonna, Miley Cyrus, in their Tn have this aspect, and in their way of communicating it is known their attitude(Mercury) "extreme"(Pluto). Many times censored.
The nuances this aspect has are many, these also depend on everything else in the picture.
These are just some hints, to understand how to "translate" them.
