SDelete on EFS encrypted folder displaying weird behavior, filling up drives when no clean drive parameter specified

Running Sdelete to delete an EFS encrypted folder on a VM environment leads to this weird behavior where it tries to clean free space.

Question: is that the normal behavior of SDelelete? I wouldn't want this to happen in production, where SDelete fills up the virtual drive and I have no control over it.

Do note that my input is sdelete -p 3 -r -s C:\temp\ToDelete

There's no parameter to clean the drive supplied in the command.

In contrast, running SDelete to delete a folder that's not EFS encrypted will have a normal behavior.

Any help/advice would be appreciated.
