Libreoffice and kde integration

[mcmurchy1917-libreoffice at yahoo.co.uk]

Why does the autogen.sh that is used to compile the  build, Linux - rpm (x86), 
version 4.1.4, English (US) have the flags -

--disable-kde4
--enable-kde

in the file LibreOfficeLinux.conf.

Is it because in the standard build  kde integration of LibreOffice is still at 
KDE3?

Or have I lost the plot completely!
