You are not comparing like with like.

If you change the href on an already loaded script element, the script content has already been added to the scripting context.

If you change it or delete it before its has loaded then, well, it hasn't loaded.

If you add something (whether it is the same as something that was transitorily there before or not is immaterial) then, if it loads, it gets added to the scripting context.
