DirMove on same volume

[hawkear@…]

+---Dirtest1
|   \---Subdir
|           somefile.txt
|           
+---Dirtest2
|   \---Subdir

DirMove("C:\Dirtest1\Subdir","C:\Dirtest2",1)

Should be:

+---Dirtest1
+---Dirtest2
|   \---Subdir
|           somefile.txt

Is:

+---Dirtest1
+---Dirtest2
|   \---Subdir
|       \---Subdir
|               somefile.txt

If Dirtest1 and Dirtest2 are on different Volumes, it works

I don't know why this functions was implemented as such but there is no error as the doc say

If the destination already exists and the overwrite flag is specified then the source directory will be moved inside the destination.

Replying to Jpm:

I don't know why this functions was implemented as such but there is no error as the doc say

If the destination already exists and the overwrite flag is specified then the source directory will be moved inside the destination.

But the directory is not moved inside the destination, it ist moved inside a subdirectory with the same name as the source directory, if it exists in the destination.
