Continuity mistake: During the fight on the Coronado's deck, Panama Hat is climbing the ladder with his back to the camera. In the next shot, when he says, 'Grab him, he's getting away!', he faces the camera. (00:13:21)
Continuity mistake: Inside the Grail's Temple, all the characters have the decapitated bodies of two Hatay soldiers and the two lion statues in front of them. However, when Indy's team is discovered and the shot changes, it can be seen from the position of the bodies and the statues in relation to the characters that they have all changed places, with the bodies now being to one side of the characters (to the left of Donovan and to the right of Indy).

Chosen answer: They're not, no. An individual doesn't become immortal after one drink - it requires them to drink regularly in order to remain alive. So neither Jones has been rendered immortal, merely healed of any wounds that they might have. But your surmise is basically correct - as the Grail cannot leave the shrine, any individual wishing to use it to prolong their life must stay there if they wish to enjoy its effects.

Also, in Indiana Jones and the Kingdom of Crystal Skull, Henry Jones, Sr has passed away before the start of the story and therefore was not immortal.
