Variations in cooking method for Jasmine rice
Yes, those are two boiling methods.
One is using &quot;right&quot; amount of water that get absorbed by rice (that indicate rice being dobe)  and second one is using excess amount of water. Both methods are valid although first one is much more water savvy.
But I have no idea why (and how) rinse cooked rice with boiling water. It's similar advice to using pasta water to help the sauce stick but properly cooked rice have enough surface on itself.
