That looks like a bug.

From

   :all ont:samePropertyAs ont:intersectionOf.

and
   { :rule6a . :p rdfs:subPropertyOf :r . :s :p :o } log:implies { :s :r
:o } .

and
   owl:samePropertyAs a rdf:Property; rdfs:subPropertyOf
rdfs:subPropertyOf .

we should get

	:all rdfs:subPropertyOf ont:intersectionOf.

Then, from

  :BigTall :all (:Big :Tall).

and rule6a, we should get

  :BigTall ont:intersectionOf (:Big :Tall).

and so on.

Maybe a namespace name mismatch somewhere?

Also: I don't see anything in your rules that
says samePropertyAs is symmetric.
