Comment (by strk):

 What would your ST_StartPoint return against a {{{ MULTILINESTRING((0 0,
 20 0, 10 5, 0 0),(100 0,  120 0)) }}} ?

 An ST_Boundary() with BoundaryNodeRule 2 would return {{{ MULTIPOINT((0
 0), (100 0), (120 0)) }}}.
 Note how BOTH start and end points are returned for the second geometry...
