Difference functionality Garmin Express versus Garmin Connect

Can anybody explain why I only get the latest positions of the GPS satellites to my watch using Garmin Express? Using Garmin Connect on my smartphone doesn't synchronise this data to my watch?

This is one of the reasons why I am still using Garmin Express to synchronise with my watch. (although I now still need Rosetta to use Garmin Express but's another issue Garmin has to solve).
