Node access create permission is overruled by edit permission

Just stumbled on this code: in node.module in node_node_access, the switch case for 'create' just falls through to the 'update' condition. This seems wrong in some way. I can think of scenarios where you are allowed to create content but not edit what you just have created. Or you are only allowed to edit content, not create it. The code as it is written now implies anyone with 'edit any' permissions is able to create content, since the 'create' permission is overruled.

switch ($op) {
    case 'create':
      $access = AccessResult::allowedIfHasPermission($account, 'create ' . $type . ' content');

    case 'update':
      $access = AccessResult::allowedIfHasPermission($account, 'edit any ' . $type . ' content');
      if (!$access->isAllowed() && $account->hasPermission('edit own ' . $type . ' content')) {
        $access = $access->orIf(AccessResult::allowedIf($account->id() == $node->getOwnerId())->cachePerUser()->addCacheableDependency($node));
      }
      break;
