Multiple objects vs. intersectionOf when defining subclasses

Hello,

When creating an ontology, I needed to assign multiple subclass relationships to one class. I came across two ways for how it can be represented and I would like to ask what the difference between the two is. I couldn't find the difference mentioned anywhere and I tried reasoning on some simple examples and got the same results. The first option is to assert all the subclass statements individually, the other option is to use intersectionOf. Examples:

1)
:Approver rdfs:subClassOf [
    a owl:Restriction ;
    owl:allValuesFrom :Request ;
    owl:onProperty :context
  ], [
    a owl:Restriction ;
    owl:allValuesFrom  schema:Person ;
   owl:onProperty :roleOf
  ] .

2)
:Approver rdfs:subClassOf [
    a owl:Class ;
    owl:intersectionOf ( [ a owl:Restriction ;
                          owl:allValuesFrom :Request ;
                           owl:onProperty :context ]
                         [ a owl:Restriction ;
                           owl:allValuesFrom schema:Person ;
                           owl:onProperty :roleOf ]
                       )
  ] .

Thank you in advance,
Jana
