We may share such information in any of the following limited circumstances: (...) access, preservation or disclosure of such information is reasonably necessary (...) >> Note the wording carefully, especially the word "or."
Dunno... i especially noted the word preservation.
It sort of slips out of context like, say a piece about oranges that also must mention "tuna fish" for some reason.
The words "share" (1st line) and "preservation" doesn't even refer to the same kind of concepts on an abstract level. Otoh, "access" and "disclosure" are quite similar to "share".
