According the paragraph you noted, the shell in question (assumed to be an 8" round, but I have seen other references, based on extensive post-war analysis, propose that this was a 14" shell) penetrated 7" to 8" of the 12.2" bulkhead before the shell, already broken apart came to a stop. Given the extremely short ranges involved, it would not be unheard of for a 8" shell to acheive this level of penetration. In any case, the round was defeated by the armor; it did not pass through. I refer you to paragraph 40 which states: "No projectile penetrated the armored box. Hits Nos. 3, 4, 17, 24, 25, and 26 struck armor before detonation and failed to penetrate."
