Eeschema - Are all power ports connected together?

In Dec 17 I posted:
The symbols discussed are in the “power” library, and note that you place them using the “Place power port” tool. Also note that the PWR_FLAG component doesn’t look like the PWR bar symbol shown here, not sure that that is. And further, the whole hidden power pins functionality is a kludge that’s obtuse to the extent of obscuring the simple task of connecting power pins to a global net that happens to be for power.

The behaviors in question are: implied attachment to a power net being offered by the “Place power port” tool possibly other behaviors I don’t know about? I see that a power port and its pin has the following attributes that might be involved: Power port component: [ ] …

… and it does get to the heart of the matter!
