[HPADM] System Node Name in "btmp" file

A bit of unusualness here,  well I haven't see it before. 
When doing a 'lastb' command on and 11.0 system, for the first time, an actual
system's node name showed up in the device field:
 
Login Name             Device                  Date
SDFMD16           <node name>      Wed Nov 30 08:14    
 
<node name> = system's node name.
The system in this case is a walkup PC on a factory floor used for inputting shop
floor data via a barcode reader into an MRP application.
 
Has anyone seen this before and is it accepted or is it not supposed to happen?
Normally I see a "pts/t-something" or "remshd"  in the device field.
 
Thanks
