I could confirm it so I digged my zypper history:

Useful info:
* libenchant-2-2 has a Requires tag for the virtual package enchant-2-backend
provided by _enchant-2-backend-voikko_ and _enchant-2-backend-hunspell_.
* enchant-2-backend-voikko has a Supplements tag and will be installed if
libenchant2-2 and libvoikko are installed.
* enchant-2-backend-hunspell has a Supplements tag and will be installed if
libenchant2-2 and libhunspell are installed.
We can see that the Supplements tags are not working because:
1) enchant-2-backend-hunspell is not being installed and;
2) the enchant-2-backend-voikko Supplements tag has a typo that prevents it
to work.
When some package uses a `Requires: $virtual_package_name` and more than one
package provides $virtual_package_name the dependency solver will check the
system, if a package which provides $virtual_package_name is not found one
will be installed.
I'm thinking since Supplements tags are weak dependencies it's being suppressed
by the Requires one. The Requires tag behavior when facing multiple
$virtual_package_name's seems to be to only make sure at least one package
which
provides $virtual_package_name is installed, if it's not one will be installed
rather than _every_ package which provides it.
