If Sakazuki knew about Oden's voyage with Roger or if he deemed it relevant, he would have brought it up considering it was his last journey as a pirate. Instead, he identified him immediately and specifically as a WB crew member showing that either he himself didn't know that Oden joined Roger for that year or that, from the marines' perspective, his relevance as a WB pirate far surpass that episode.
If a marine officer associates him with WB first, it goes without saying that the few people who know about him, heard of his deeds as a a member of that crew specifically.
