Level3 are the origin AS for 4.2.2.2 - they're obviously not singlehomed so 
this isn't a suitable comparison.

In any case, the purpose of my statement was to draw a line between Anycast to 
an AS you're singlehomed on vs. Anycast when multihomed - in the latter case 
you may wish to do more work to ensure desirable bestpath selection, I wasn't 
trying to state nor imply that Anycast when single-homed doesn't count as 
Anycast.
