Note the wording "purge". I'm guessing that the 10.0 package was removed
(but not purged). And that a later purge step of the already-removed package
caused the observed behaviour.

So to try to reproduce you could just apt-get remove mariadb-server-10.0 (or
apt-get install mariadb-server 10.1 without --purge option). And then
afterwards try apt-get purge mariadb-server-10.0.
