That theme is actually MH2's snowy mountain battle and 'technically' is Blangonga's theme.

I've played MHdos and Kushala never had two theme, from my understanding the uploader of the video Drake mentioned above got mistaken since this song plays during MH2's intro and it feature Kushala prominently.

Sorry to further necro'ing this blog, but I really think this misunderstanding should be cleared by now.
