You're absolutely right, and I think the scene with Percival fighting a "Southron" soldier in The Sword in the Stone: Part 2 was a reused shot from The Coming of Arthur: Part 2 when Percival fought an Immortal soldier (who probably was the soldier with the helmet as you said) before Arthur said "If we're to go down, we'll go down fighting, for the love of Camelot".
