because it won't. :) mathematica function definitions expect
expressions with Head Symbol for function argument patterns, Subscript,
in this case, is not a valid Head. If you really want subscripted
function variables, check out the Notation package. this is definitely
not a user friendly way of going about this, but it should work if you
_really_ need it.
<<Utilities`Notation`
See the documentation of the notation package for more info.
