Codex:

Determines if the image meta data is for the image source file.

The image meta data is retrieved by attachment post ID. In some cases the post IDs may change. For example when the website is exported and imported at another website. Then the attachment post IDs that are in post_content for the exported website may not match the same attachments at the new website.
