Immortal Choice

[Barandur of Nargothrond]

“But when all was spoken, Manwe gave judgement, and he said:’In this matter the power of doom is given to me. The peril that he ventured for love of the Two Kindreds shall not fall
upon Earendil, nor shall it fall upon Elwing his wife, who entered into peril for love of him; but they shall not walk again ever among Elves or Men in the Outer Lands. And this is my decree
concerning them: to Earendil and to Elwing, and to their sons, shall be given leave each to choose freely to which kindred their fates shall be joined, and under which kindred they shall be
judged.”

Elrond chose to join his fate with the elves and Elros to that of men. The question is why did Elrond's children continue to have a choice when it is never mentioned that the children of Elros don't seem to have the same option?
