"Identifier is not defined" when using variable in gpu.js - why?

I am puzzled by an error I get with gpu.js. I am trying to do GPU-based calculations of nearest point on line, as I have to process hundreds of points against a line with thousands of segments.

See in-progress code at https://codepen.io/simonecesano/pen/rNeVKee

I stumble on the issue that - at line 48 if I do this:

var ptos = geodistance(fx, fy, sx, sy);
    
return geodistance(fx, fy, sx, sy);

everything works but if I do this:

var ptos = geodistance(fx, fy, sx, sy);
    
return ptos;

I get Uncaught Error: Identifier is not defined in gpu.browser.js

Why is that, and what do I have to do to fix it?
