It makes sense, as any object in ActionScript is an instance of
a class, which may export an interface. The interface is an as_object
itself. Note that player2.swf is using registerClass and IIRc also
'extends' which are both used to design inheritance chains.

Try to find out more about the object those functions are registered
against. Is it a 'properties' object ? Can it be it's being replaced
by an explicit override of 'properties' ?
You're on a good track by reducing the testcase, but you need a way
to make your tests verifiable against the proprietary player.
What we use with Gnash is a textarea and a set of utility functions
to perform some checks, like: check_equals(typeof(myObj.setMovie), 'function').
You can get all the facilities by including the Dejagnu.swf file in your test,
either as a built-in clip or by using an IMPORT tag (symbol name is 'dejagnu').
