It's an overloaded term. The `get` on this line is [from Protractor's `ElementArrayFinder` prototype](https://github.com/angular/protractor/blob/master/docs/api.md#api-elementarrayfinder-prototype-get), whereas the one used on line 77 is the built-in `get` getter/setter [available in all Javascript prototypes](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/get), which Astrolabe utilizes heavily.
