TL;DR

When you place a ghost belt on top of a real one, a redirect/upgrade/downgrade order will be placed for the real belt if it is in a different direction and/or a different tier. This does not work for blueprints.

What ?

When belts in a BP are placed on top of real belts, the logic is the same for manually placed ghosts.

Why ?

This makes the placement of ghost entities more consistent.

Why only belts? No inserters? Assemblies? Groundplates?

But then if you want the existing belts left alone, how would you do it?

Whereas if you want to get rid of the existing belts, you can also deconstruct them first.

One answer is for it to be optional behaviour, with a modifier key combination when placing a blueprint to activate it... similar has been suggested (many times) before; see 59554.

Deconstruction means the belts will be stopped, removed (along with any items on them) and replaced instead of upgraded/rotated in place. This is presumably the reason for the behaviour with manually placed ghosts, which is not just for belts but I think all items that can be "fast-replaced".
