2 fact table fields linking to 1 reference table

Thank you. I watched that video and a few others on duplicate versus reference. What I found interesting was when you create a reference,  the query still pulls the original data again to build that reference. I would have thought it would have pulled it's data from  the original query and not gone back to the source again, So if I understand correctly weather I use reference of duplicate the customer master source will be read twice. This will work just fine I just wanted to be sure I was not missing a better way to accomplish the task.

FYI here is the video I watched that did a good job of what is really happening behind the scenes when you use reference.
