It's because templated functions are really just syntactic sugar.  So:

void foo(T)(int x){}
void foo(T)(int x, float y){}

Is really seen by the compiler as:

template foo(T) { void foo(int x){} }
template foo(T) { void foo(int x, float y){} }

Now it looks obvious that there should be an error, because it's the 
templates that are at top-level, not the functions.
