The current Widow/Orphan and Keep Lines Together is dysfunctional.
Apparently, Keep Lines Together only keeps lines of next para or prev para or something: it does NOT actually keep the selected lines together!! How stupid is that????

The "Keep lines together" option in the paragraph format prevents this paragraph from being split across two different pages. This option applies to the paragraph, not to the selected lines.
You can learn more about this paragraph format option in the MS Word document formats here.
