Note the "--resource" parameter being present.
Which will include results from other(!) databases apart from the RIPE
NCC database. In this case the RADB-GRS database.
The 'source:' also denote this fact.

Nb: You can see http://www.irr.net/docs/list.html#RIPE which other RIR
databases the RIPE NCC mirrors.
