As Andreas said.

This is the manage_pasteObject pydoc (you can read with DocFinderTab):

    Paste previously copied objects into the current object.

    If calling manage_pasteObjects from python code, pass the result
of a previous
    call to manage_cutObjects or manage_copyObjects as the first argument.

    Also sends IObjectCopiedEvent and IObjectClonedEvent or
IObjectWillBeMovedEvent and IObjectMovedEvent.

Also I think (please, check... I'm not sure) that if you want to use
cut/paste in the same transanction, you to put a
transaction.savepoint() between two operations.
