This is not doing quite what I think you think it is doing.
Use 'echo' to show what arguments are being passed to the command.

  echo cp -rvf !(*~|.scratch) /tmp/dir2

I expect this to show that the shell has already expanded that shell
file glob to match (or not match) the files in the current directory.
Because the -r option is specified if one of those is a directory then
the full contents of the directory will be copied recursively.

This type of operation is much better done using the modular tools
such as already posted by others.
