No, he isn't.

There seem to be some unstated assumptions here.

What he is saying is 'if you try to connect anycast address PRFX::/64, the 
ICMP unreachable (or whatever) message comes back from PRFX::X/64 (unicast 
address on the node)'.

This applies to RFC2460 anycast only, and depending on source address 
selection, possibly pseudo-anycast.

See above.  There should be no nodes which have only RFC2460 anycast
address(es), as they must not use it as a source address.
