Am I right in thinking that Google public DNS simply does not cycle the
multiple records on a round-robin host. There have been a few threads on
this (i.e. google "round robin 8.8.8.8")

In fact for A or AAAA records it apparently always returns them sorted
by address. The order seems to be consistent for other record types,
but it isn't so obvious just what it is.

One can certainly consider this to be an unfriendly act on Google's part.
The safer thing to have done would have been to use a new random order
(better than "round robin" any day) for each response.
