I would think that the following sentence from the HISTORY EXPANSION
section of the man page would be more relevant:
History expansion is performed immediately after a complete line
is read, before the shell breaks it into words.
I will see whether that sentence needs to be added to the history
texinfo manual.

In bash-4.3, this is restricted to the case where the exclamation point
immediately precedes the closing double quote. In effect, an open double
quote temporarily adds double quote to the set of characters that inhibit
history expansion when found immediately after the history expansion
character.
