Yup, that's correct - it is only possible to merge 2 edges when there are no other edges connected at the spot that they touch. If there are other edges also radiating out from the same connection spot you can't merge them together because the other edges are expecting to be part of a loop along with the ones being merged, and that would not be possible anymore if they did not end in the same spot.

I'm not sure if I completely understand this part, but the Rebuild command generates a curve as its output. In many cases you can also select an edge as the input to any command that takes curves, but if the command outputs standalone curves you will get a new curve object generated as the result, the edge is not modified in a case like that.

Some commands do work differently if you select edges instead of curves, it depends on the particular command.
