$geoNear on multiple geo index keys collections

In the documentation here it says that in v4 we can have multiple geo indexes in the collection for the $geoNear stage. If so, then I think this should be pointed out in the lessons.
Or did I get it wrong?

As you can see, this class uses version 3.6. IMO adding notes on versions that are not otherwise mentioned or supported in the class would be both confusing and a waste of time.

However, if you feel strongly on this, I would suggest that you use the “Report an issue” tab at the bottom of the screen to make this suggestion. That goes directly to the curriculum team who are the only folks who could implement this.
