I don't think that statement is accurate (though I could be wrong). As I made my way up from C- to A- in DI, each recruit who had a preference for success gave me the exact same rating within that particular recruiting season. When I was C-, Wants Rebuild was Good and Wants Success was Bad. When I was C+, both were Neutral. When B, Wants Rebuild was Bad and Wants Success was Good. At A-, Wants Rebuild is Very Bad and Wants Success is Very Good.
Note, even if your prestige changes between RS1 and RS2, this preference does NOT change.
Also note, in DII, what prestige levels qualified for each level differed from DI.
