How to do nested if else

Is there way to do such nested if rules? Is there setting to make the parent rule expression also evaluated even if there are nested child rules?

if(loyaltyFactor > 4)
{
    if(totalOrder > 3)
    {
    ...
    }
   else
    {
    ...
    }
}
else
{
...
}

            "ErrorType": "Error",
            "RuleExpressionType": "LambdaExpression",
            "Expression": "input2.totalOrders > 15"
          }
        ]
      }
    ]
  }
]

Review the nested Rules JSON and the C# conditional example in the issue; determine whether the parent expression is evaluated alongside child rules and how nested if/else is represented. A complete outcome would be a clear supported configuration or documentation answer, with behavior confirmed for the shown loyaltyFactor and totalOrders cases.
