Why are there unlocated origins that are within the search tolerance?

When I was double checking the results of my OD Cost Matrix, I found some unlocated origins that were within my Search Tolerance. I was using the Measure tool in ArcMap to do this check.

I set the search tolerance to 2500m when creating the OD Cost Matrix Layer and when adding the Origin Locations. I have no restrictions, I unchecked "Exclude restricted portions of the network", and I have no Default Cutoff Value set. I'm using ArcGIS v.10.

I want to make sure I understand why this is happening before I proceed with the rest of my analysis, which will likely take a long time.

Thank you to anyone who has any suggestions or comments!
