Unexpected match of structures

[pamelafox]

This structure:

fill(_);
if ($ifCond) {
    fill(_);
} 
rect(_);

matches true to:

if (mouseIsPressed) {
    fill(255, 0, 0);
}
fill(0, 255, 68);
rect(0, 0, 400, 200);

I replicated on http://khan.github.io/structuredjs/, which I recently pushed, so it should be up to date.

Still matches if rect(...); is removed.
Does not match you switch it around:
if($i) { fill(_); } fill(_); and fill(1,1,1); if(345) { fill(3,3,3); } returns false
