I would not bother myself with that sentence. It is what it is meant for: a "suggestion" or a "description" of the product - maybe more exactly the intent or the idea of the creators when separating the two.
"Suggestion" and "recommendation" are not legal terms (well this latter one has some EU usage but only for governments).
It was disallowe to use SU Free (beta) when it came out with version 5 right after Google acquired SU. Then it was explicitely allowed during SU 6 and this explicit sentence was removed when SU 7 (and the new SU Google site) came out (so not with SU 8 that was just - or rather EXACTLY - a year ago).
