Finding linked topics in DBPedia using SPARQL

Consider we have these two topics:

http://dbpedia.org/page/Jason_Furman and http://dbpedia.org/page/London

For the first topic, Jason Furman, we can see on the property almaMater that he went to:

http://dbpedia.org/page/London_School_of_Economics

And looking at London School of Economics we see that it has London as value of the city property.

So my question is: If we have two topics, A and B, how can we find property values of A that has topic B in any of it's properties?

select distinct ?a ?p ?y ?q ?b where {
  values ?a { dbpedia:Jason_Furman }
  values ?b { dbpedia:London }

  ?a ?p ?y .
  ?y ?q ?b .
}

SPARQL results

(Note that there are two results because there are two such properties: dbpprop:almaMater and dbpedia-owl:almaMater.)
