clarification about require entry in fields based on sel

I posted a question to the reply to my earlier post about require entry in fields based on selection in another. I did not get a reply to my last question so I thought it might be best to start a new post. Below is my question regarding require entry in fields based on selection in another.
If I need a second set of required based on if the user selects 'Forwarding Job', would I repead as I've done below?
var ctrl = Runner.getControl(pageid, 'ClosingJobField');

var ctrlComplete_Date = Runner.getControl(pageid, 'Complete_Date');

var ctrlComplete_Time = Runner.getControl(pageid, 'Complete_Time');

var ctrlStatus = Runner.getControl(pageid, 'Status');

var ctrlInvoiceNumber = Runner.getControl(pageid, 'InvoiceNumber');

var ctrlQCedBy = Runner.getControl(pageid, 'QCedBy');

var ctrlClosedBy = Runner.getControl(pageid, 'ClosedBy');
function func() {

if (ctrl.getValue()=='Closing Job'){

ctrlComplete_Date.addValidation("IsRequired");

ctrlComplete_Time.addValidation("IsRequired");

ctrlStatus.addValidation("IsRequired");

ctrlInvoiceNumber.addValidation("IsRequired");

ctrlQCedBy.addValidation("IsRequired");

ctrlClosedBy.addValidation("IsRequired");

}

};
ctrl.on('change', func);
var ctrl = Runner.getControl(pageid, 'ClosingJobField');

var ctrlFowardedBy = Runner.getControl(pageid, 'FowardedBy');

var ctrlForwardNotes = Runner.getControl(pageid, 'ForwardNotes');
function func() {

if (ctrl.getValue()=='Forwarding Job'){

ctrlFowardedBy.addValidation("IsRequired");

ctrlForwardNotes.addValidation("IsRequired");

}

};
ctrl.on('change', func);
