I think this typo appeared in the latest Rhino update.

def DuplicateEdgeCurves(object_id, select=False):
"""Duplicates the edge curves of a surface or polysurface. For more
information, see the Rhino help file for information on the DupEdge
command.
Parameters:
object_id (guid): The identifier of the surface or polysurface object.
select (bool, optional): Select the duplicated edge curves. The default is not
to select (False).
Returns:
list(guid, ..): identifying the newly created curve objects if successful.
None: if not successful, or on error.
Example:
import rhinoscriptsyntax as rs
obj = rs.GetObject("Select surface or polysurface", rs.filter.surface | rs.filter.polysurface)
if obj:
rs.DuplicateEdgeCurves( obj, True )
rs.DeleteObject( obj )
