there is no misunderstanding
the legally defined admin boundary is at a particular place
but the question is 
does it move when the feature (road, railway, river) moves
or is staying at the original place until the law moves it?

Exact example:
The southern bank of the Murray River is the border between 2 states.
Where the river has been flooded by building a dam the southern bank has 
moved. (Yarrawonga-Mulwala region)
Legal answer for this boundary - the boundary did not move.
