No, that's correct. Via the API, all points come in blocks, normally
delivered in logical order but not with any timestamps or other information.
You can open your own GPX files (or download the original files from OSM if
they were made public) if you want to keep them on separate layers. With the
original GPX files you can effectively do more in JOSM than with the data
via the API.
