So you're nit-picking over the phrasing of the sentence, but should instead focus on the spirit/meaning behind it.

It's illustrated in their example below that they if you say you're having a baby, meta can send some type of distilled ad-keywords to its servers (eg `[mother, baby]` if it knows the user is a woman based on their name/profile, but probably more sophisticated than that). The message you sent is still technically end-to-end encrypted, though,
