Yes, you're right about that of course. To the user that doesn't make a
difference, I guess I got my head stuck in the code ;-)

That would then be a SOURCE-pre-snap-indicator.

Yes, that's right. The main (or even only) use of this is when multiple
snap sources are available which are very close together, at one single
side of the shape (for example the bounding box corner and the node of a
rectangle). The mouse pointer might be covering all of them, which makes
it hard to accurately select the desired snap source. When using "snap
closest to mouse pointer only", you will have to zoom in to reliably
control the snap source. Using Inkscape's default snapping mode however,
Inkscape will first snap considering all candidate snap sources, then
show you which has snapped, and finally allow you to change which snaps
by moving the mouse a little. I've got used to that and like it that way
best, but I can imagine not everyone feels the same. That's why it's
been made configurable :-)
