Must one raise (or keep lowered) the hands during ritual washing to prevent first-waters from flowing back past the wrist joint?

BlessingsNetilat YadayimTechnique

Synopsis

The Talmud requires raising the fingertips upward during handwashing so impure first-waters cannot flow back past the wrist joint and re-defile the hands. Authorities debate whether lowering from the start is equally valid, whether washing up to the wrist joint eliminates the concern, and whether pouring three times renders the caution unnecessary.
