Reuse option in FileCopy migrate process plugin not work with remote files

I have tested that code:

process:
    uri:
      plugin: file_copy
      reuse: true
      source:
        - source_file_path_remote
        - destination_file_path

In the transform method of file_copy process plugin the download process plugin is called when a source file is remote. So the file is downloaded ignoring the reuse option.
