I believe the idea is to force/require a tail call optimization, rather than just hoping a JVM heuristic will kick in (assuming I understand correctly). See http://blogs.sun.com/jrose/entry/tail_calls_in_the_vm for a more detailed discussion. To quote from Arthur's email to the MLVM mailing list (which I linked to previously): "To mark a call as tail call the programmer emits a 'wide' byte code before the various invoke... instructions."
