I think I have the explanation:
(I've added echo's to the postinst script for that and saw that the
dpkg-divert is not called so ->).

The problem is that the postinst checks for [ -f /usr/bin/vim.org ].
This file does not exist because when vim was unpacked, it removed
/usr/bin/vim.org as it's no longer shipped (/usr/bin/vim is no longer
shipped, but it's diverted). The postinst is run after that and so
doesn't call dpkg-divert.
