Saving WorkItem - SaveFlags

in 2010 Beta 2 the new TFS SDK provides an overloaded method for WorkItem.Save(SaveFlags). SaveFlags is an enum with only 2 values: None and MergeLinks. Does anybody know what the MergeLinks option actually does? Can'开发者_C百科t find it anywhere... Thanks in advance.

From MSDN article(http://msdn.microsoft.com/en-us/library/ff734890.aspx), it removes the errors of adding/removing links that have already been added/removed.
