Your argument seems plausible. However, in my case and several others the HUD and libreoffice actually do communicate. But only in a "fresh instance" of libreoffice in which no document has been opened or created.
Let me explain with an example: I launch libreoffice writer from the launcher, wait serveral seconds, bring up the HUD and start typing. For example "recent thesis" to open my file thesis.odt which is listed in "Recent Documents" in the "File" menu. The HUD shows all options in the libreoffice menus as would be expected, no bug noticed so far.
However, once the file is opened the HUD does not work anymore.
Therefore I assume that (even though I agree the ubuntu HUD isn't very stable) this particular bug is in LibreOffice. After all, it is a change in libreoffice that makes the HUD not work properly.
