In JOSM, what does the "Unconnected nodes without physical tags" warning mean? In this case, I am attempting to create a a POI.

I expect the full warning message is "No Tags - Unconnected nodes without physical tags"?

The warning means you've added a node somewhere without any tags set on it.

The warning comes from the JOSM "validator". You can read about the validator and different error messages on the JOSM Validator wiki page.

Note that the validator runs prior to upload. But you can also run it at any other time if you show the validator panel. This has the advantage that you and right-click and "zoom to problem" on any particular message, to help figure out what it's talking about.

In this case, the issue was that I unintentionally created two nodes, one without any tags. JOSM caught it before saving.

If you do try to upload and the "Suspicious data found" box pops up just click the "Cancel" button and the validator panel opens as Harry says above. Make your corrections and try uploading again, on complicated issues it might take several corrections to get things right. Get really stuck then back out by deleting the "data layer" in the layers panel, that removes any chance of inadvertently uploading bad data.
