iOS backup behavior

I lost my iCloud backup after doing this: it that normal?

#1) backup to iCloud my iPhone SE 128

#2) erase everything

#3) recover to that SE128 the backup of an older iPhone 5s (same user)

#4) Now I no longer see the first backup so basically I have lost everything I kept on my SE128, the only backup that are listed as iPhone SE are those made after #3, which are the backups of the older 5s.
