Hi Brian, curves that are joined together and select as a single piece are definitely connected.

The part that you don't get a true indication of is whether the curve is closed or not. That is - there can be a gap between the very start and very end of the curve, even though each of the segments of the curve is attached to another segment. That's what happened in your other case recently.

Here is a visual explanation:

Below I have a curve made up of 4 segments. When I click on the curve, the whole thing highlights:



This definitely means that those 4 pieces are connected end to end.

Now I have edited the curve to drag that open endpoint pretty close to the start:



Even though it looks like a closed curve at a glance, it is not, there is still a gap there just as in the first image, it is just smaller and harder to notice.

That is the kind of connection (between start and end) that you can't automatically be sure of.

The connection between all the other segments you can be sure of.
