I think the reference to "at least one <see> entry" is probably a typo, because the grammar only allows one <see> element in an indexterm.
It should be possible (but maybe not too easy) to get the Chicago Manual style with a stylesheet customization that looks for multiple indexterms with the same term(s) and <see> elements. That approach doesn't change the grammar, but would give you the visual result you want. However, it's not unreasonable to allow multiple <see> elements on one <indexterm>. If you think that's important, you can propose an RFE (Request for Enhancement) on either SourceForge or (preferably) Github for consideration in the next revision of the DocBook standard. If you're not sure how to do that (or don't have permissions), let me know, and I'll file one (I think it's worth considering).
