When I "copy as citation" a section of a commentary into a word processor (Word, Google Docs), it does not include the section of the reference work
For example Barnes' Commentary for Matthew 1:19 ("and her husband Joseph a just man") has the following Barnes's commentary
A just man. Justice consists in rendering to every man his own. Yet this is evidently not the character intended to be given here of Joseph. It means that he was kind, tender, merciful; so attached to Mary, that he was not willing that she should be exposed to public shame. He sought, therefore, secretly to dissolve the connexion, and to restore her to her friends without the punishment commonly inflicted on adultery. The word just has not unfrequently this meaning of mildness, or mercy.

The citation does not state that this section is from Matthew 1:19 in Barnes Notes. a person reading only the citation would have to search all of Barnes Notes to find the specific passage that was copied.
