yes, why not

right, that is a different issue
we get (using owl-rules importing rdfs-rules)

 {
  <http://www.agfa.com/w3c/euler/rdfs-rules#rule8> .
   {
    <http://www.agfa.com/w3c/euler/rdfs-rules#rule6a> .
    :B :foo :C} log:implies
  {:B rdfs:subClassOf :C}.
   {
    <http://www.agfa.com/w3c/euler/rdfs-rules#rule6a> .
    :A :foo :B} log:implies
  {:A rdfs:subClassOf :B}} log:implies
{:A rdfs:subClassOf :C}.
