You did it right. A book I have [Windows 98 Developers Handbook, Ezzell & 
Blaney, Sybex, 1998] says

  Do not under any circumstances free memory after transferring
  a data object to the clipboard. [...] The result of calling
  GlobalFree would delete the item from the clipboard. Instead,
  once a data item has been transferred, ownership of the item
  has also been transferred, and the local handle should not be
  used or tampered with further.

You are correct in guessing that the next time an application calls 
EmptyClipboard the global memory is freed by the Clipboard itself.
