Well, Join is kind of like a grouping function, it forms a curve that has all the joined parts as segments within it.

Join does not itself attempt to simplify or greatly change the structure of the pieces being joined.

If you have a badly segmented and fractured curve with messy control points, tons of little pieces, etc... then Join does not automatically solve that, your joined result will still have a ton of individual segments inside of it instead of simplified cleaner segments.

Some kinds of surfacing operations try to preserve the segmented nature of your input curves, so if you have a overly fractured segmentation you will also get fragmented results in the sweep (made up of many surface pieces instead of fewer for example).
