This new facility was introduced in 6.4 and enables review of the full content of one sheet as a single page in PDF export. A suitable description should be added to the Help files.
Page is https://help.libreoffice.org/7.0/en-US/text/shared/01/ref_pdf_export_general.html

*** Bug 138490 has been marked as a duplicate of this bug. ***
On the duplicate bug, I proposed the following text: Ignore each sheet's paper size, print ranges and shown/hidden status and put every sheet (even hidden sheets) on exactly one page, which is exactly as small or large as needed to fit the whole contents of the sheet (not only its print ranges). The release notes actually contain a good description, with screenshots, etc. Except for the option apparently having been renamed, maybe the help page can reuse content from there.

I think that is not correct. What happens is that the size of the page is fit to the contents. So the contents doesn't get smaller or bigger to fit e.g. an A4 page, the page size is not A4 but "whatever is needed to have all the content, no more no less".
