Difference between 3 user license and 1 user 3 pc license

Sorry, can't find the answer to this anywhere. I know a 3 user license allows 3 different people to use the product on 3 different computers so does a 1 user 3 pc license mean it has to be installed on 3 pcs at one central location (home) or could I install a 1 user 3 pc license on 3 different computers in 3 different cities?

 

Thanks!
