What is the second tk2d subshader/pass for?

Hi all,

Sorry to be a bother but I was just wondering, why do the tk2d shaders have two subshaders/passes?
Are both passes called when rendering a sprite? If not, how is one prioritized over the other? Target hardware?

Thanks very much in advance to anyone who can educate me

It shouldn't be used any more. Its just there as a fallback for fixed function devices that didn't support programmable shaders in the past.
