You should run File->Update selection if you want to refresh the data in the current selection with the data the server currently holds. JOSM won't overwrite the local data, but it may detect, that current object versions from the server collide with objects you are working with locally. In this case, JOSM will create conflicts. You will have to resolve them after the update is finished. Your local edits aren't lost.
This action is disabled unless the current selection isn't empty.
