What happens if Switch LOV condition is updated?

Hi all, We are using JDeveloper 12.2.1.3.0, for which I have questions below

In some part of our code we are executing below method if we check or uncheck a checkbox.

public void selectAndUnselectTable(boolean isSelected) {

    String l_Poshipto = null;

    DCIteratorBinding iterBind1 = ADFUtils.findIterator("DefLinesVO1Iterator");

    String Poshipto = (String) iterBind1.getCurrentRow().getAttribute("Poshipto");

    if (Poshipto.equals("DropShip")) {

        l_Poshipto = "D";

    } else if (Poshipto.equals("Vendor")) {

        l_Poshipto = "V";

    } else if (Poshipto.equals("Warehouse")) {

        l_Poshipto = "W";

    }

    iterBind1.getCurrentRow().setAttribute("SelAll", "FALSE");

    String Bypass = (String) iterBind1.getCurrentRow().getAttribute("Bypass");

    Object Plandate = (Object) iterBind1.getCurrentRow().getAttribute("Plandate");

    String Company2 = (String) iterBind1.getCurrentRow().getAttribute("Company2");
