Can an owl: class and owl: a restriction have to be removed from the definitions of the restriction classes?

Question

Are these statements the same? Is there a problem if I remove owl:Restrictionand owl:Class. they seem redundant, but this is always the way I see examples on the Internet. owl:onPropertyhas a domain owl:Restriction, and owl:Restrictiona subclass of owl:Class.

:myClass owl:equivalentClass  
[a owl:Class ;
          owl:intersectionOf (
          [ a owl:Restriction ; owl:onProperty :hasProp  ; owl:allValuesFrom  :SomeOtherClass ]
          [ a owl:Restriction ; owl:onProperty :hasChild ; owl:someValuesFrom :SomeOtherClass ] ) ] .



:myClass owl:equivalentClass  
[owl:intersectionOf  (
  [ owl:onProperty :hasProp ; owl:allValuesFrom  :SomeOtherClass ]
  [ owl:onProperty :hasProp ; owl:someValuesFrom :SomeOtherClass ] )
] .
