programmable structures: Wrong explanation for unitdata-scan

In aai-programmable-structures_0.6.6, the item description for unitdata-scan seems to be wrong.
Though it says it can input Player ID, nothing comes out.

`unitdata-scan=Input Vehicle ID or Player ID (Virtual Signals Tab), selects the nth entity of that type in order of placement or use a negative value to select in reverse order (most recent first). Outputs any signal data that is stored in the vehicle. Stored signals are used for the vehicle item inventory targets when interacting with Haulers, or can be used to differentiate units, signify roles, etc.`
