Are all the UIDs on a key supposed to be equal?

You can also revoke uids on your key; which indicates juste a change
of address, but you keep being the same person. If you look at my key
(0xF7001FC7 on public servers), you see it bears following Ids:

gpg: using classic trust model
pub   1024D/F7001FC7 1998-12-14
uid                  Erwan David <erwan at rail.eu.org>
uid       [ revoked] Erwan David <Erwan.David at teaser.fr>
uid       [ revoked] Erwan David <Erwan.David at trusted-logic.fr>
uid       [ revoked] Erwan David (Adresse Perso) <Erwan.David at teaser.fr>
sub   2048g/016C3D2F 1998-12-14
