If that was in the Sources section, as it is on that profile, that would definitely show what was stated in each place. Since that is a subscription site that everyone doesn't have access to, it is stated what was found in each volume, which is great. Otherwise people wouldn't necessarily know what information was show exactly.
. If that were to be put into inline citations, the entire source could be put into one inline citation with the appropriate vol, page, etc. and the other inline citations could state Greenfield Hill Church Records with the Vol, page, etc without the rest of the source, I think, because the user should be able to determine the rest of the source citation from the other citation that would be in the Sources section.
