No, it's good. Your synopsis is accurate.
I can't find the sutta just at the moment, but I recall it's towards the end of either the Majjhima or Samyutta Nikayas.
It's often cited as an counter-example to the Buddha's alleged omniscience (the range of which is debatable).
"Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'." (Snp 3.6)
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
