Eheheh, you're right Perma, it's a bit confusing to be honest !
Anyway it all comes with priority rules: Level 1-2-3. Whenever a second failure of this type happens while already perfoming an ECAM action, you can either HOLD ECAM and check with QRH/OEB's, or simply continue doing actions in the reported order (eg. new Level 3 warning over the old Level 2): should a DUAL ENG BLEED FAULT caution be displayed just after a 1/2 ENG BLEED FAULT, the right new ECAM sequence will automatically overcome the old one, belonging to a lower level.
The FCOM sections related to ECAM Sequence and Priority Rules are 1.31.10 and 1.31.25.
Hope that helps,
