I just confirmed that this does not happen running Office 2011 under Mavericks. In Mavericks, only the fonts that are enabled in Font Book show up in the Word ribbon font pull down menus. Under Yosemite, the Font Book application becomes almost useless in conjunction with the Offices apps (haven't tested under Yosemite with only Office 2011 installed).It is not only Word. All MS fonts are duplicated in all of the .apps (eg /Applications/Microsoft Excel.app/Contents/Resources/Fonts). This is (mainly) why the apps are so big. Presumably in the final version will use the ones in /Library/Fonts/Microsoft rather than duplicating them.
