Yes - that is a good use

When the link is set up to the Explore website on the XT, Stored Waypoints come from the Explore App. Exactly as you described.
If Explore is not set up, Stored Waypoints come from the route that has been created in Basecamp and transferred to the XT. They appear in Favourites (sometimes called 'Saved') and then show up on the map as square, green icons much larger than the Explore style icons. The original poster referred to 'favourites' rather than 'waypoints' - so I assumed that he did not have Explore set up.
Currently, I do not have Explore set up on my unit. It doesn't offer me anything that I want to use. But that isn't a recommendation. I can see that for some people it has a lot of attractive features - particularly tha ability to creat a waypoint using the explore app on a smartphone.
For anyone looking in, there are about 9 illustrated pages on these features that I put on this site here:
