Uh huh, and yet seto and other characters keep saying "you're still you despite you soul being rejoined". Emet only saw that vision because he's already being sentimental enough since we're reincarnation of Azem.

The sundered souls may still retain its previous "color", hence why they can uplift sundered being into ascian (mitron, loghriff, etc.), but they are still not the same person as the original one due to the reincarnation.

Ancients soul that arguably can be brought back 100% are the ones trapped inside zodiark since they retain their "self". The rest have been reincarnated many times. Rejoining only allows them to make the sundered to be whole again soul and aether wise.
