Here's my guess.
The collected data is stored by IP address. When you run snmpColDump, it
reads the file of data for all addresses, then looks up the host name for
each address it finds, and hence gets a match with your fgrep parameter
(the new nodename).
I would guess that a display function that requests the data by IP address
will work.
Was the node rediscovered with a different address (for the SNMP agent)?
That's the only way I can currently explain your orphaned data.
