Implementation of PackageableElement.conformsTo is faulty

The OCL implementation of PackageableElement.conformsTo is incorrect (copy/paste errors?):

   if (self.oclIsKindOf(AnnotationType)) then
    self.oclAsType(AnnotationType).extension.extending(e)
   else
    if (self.oclIsKindOf(ComponentType)) then
     self.oclAsType(AnnotationType).extension.extending(e)
    else
     if (self.oclIsKindOf(GateType)) then
      self.oclAsType(GateType).extension.extending(e)
     else
      if (self.oclIsKindOf(GateType)) then
       self.oclAsType(StructuredDataType).extension.extending(e)
      else
       false
      endif
     endif
    endif
   endif

Should be

   if (self.oclIsKindOf(AnnotationType)) then
    self.oclAsType(AnnotationType).extension.extending(e)
   else
    if (self.oclIsKindOf(ComponentType)) then
     self.oclAsType(ComponentType).extension.extending(e)
    else
     if (self.oclIsKindOf(GateType)) then
      self.oclAsType(GateType).extension.extending(e)
     else
      if (self.oclIsKindOf(StructuredDataType)) then
       self.oclAsType(StructuredDataType).extension.extending(e)
      else
       false
      endif
     endif
    endif
   endif
