Narrative:
On climb out from ZZZ in the high 20s; we experienced an ECAM air engine 2 bleed fault and a fault light in the engine 2 bleed. We followed the ECAM actions; which had us bring the X bleed to open. We then followed the QRH guidance. Since the fault light was illuminated after selecting engine bleed off; we considered our condition as that of the first 'if' bullet. We reset the engine 2 bleed by selecting engine 2 bleed on. 5-10 seconds later; the engine 2 bleed fault light came back on. 20-30 seconds after that; engine 1 bleed fault light came on; along with both pack fault lights. We began an immediate descent; and in the descent; I successfully reset the engine 1 bleed and both packs. We diverted to ZZZ1 after consulting with dispatch and maintenance. On the ground; maintenance told me engine 2 bleed failed from a bad BMC2 (bleed air monitoring computer); and engine 1 bleed from an overpressure. My feeling is this overpressure resulted from us resetting engine 2 bleed with the X bleed open (from the ECAM actions). I believe the QRH guidance is either poorly worded or incorrect. In my mind; I was to follow the first 'if' bullet. The fault light was on after the engine 2 bleed was off; so I waited for it to extinguish then selected engine 2 bleed on. I now believe (after talking to maintenance and an airbus captain) I should have followed the second 'if' bullet. This would have prevented the overpressure situation on engine 1 bleed.

Title: A321 pilot reported a dual bleed air fault condition the resulted in a diversion to the nearest suitable airport.
Narrative: On climb out from ZZZ in the high 20s; we experienced an ECAM AIR ENG 2 BLEED FAULT and a fault light in the ENG 2 BLEED. We followed the ECAM actions; which had us bring the X BLEED to OPEN. We then followed the QRH guidance. Since the FAULT light was illuminated after selecting ENG BLEED OFF; we considered our condition as that of the first 'If' bullet. We reset the ENG 2 BLEED by selecting ENG 2 BLEED ON. 5-10 seconds later; the ENG 2 BLEED FAULT light came back on. 20-30 seconds after that; ENG 1 BLEED FAULT light came on; along with BOTH PACK FAULT lights. We began an immediate descent; and in the descent; I successfully reset the ENG 1 BLEED and BOTH PACKS. We diverted to ZZZ1 after consulting with Dispatch and Maintenance. On the ground; Maintenance told me ENG 2 BLEED failed from a bad BMC2 (Bleed Air Monitoring Computer); and ENG 1 BLEED from an overpressure. My feeling is this overpressure resulted from us resetting ENG 2 BLEED with the X BLEED OPEN (from the ECAM actions). I believe the QRH guidance is either poorly worded or incorrect. In my mind; I was to follow the first 'If' bullet. The FAULT light was on after the ENG 2 BLEED was OFF; so I waited for it to extinguish then selected ENG 2 BLEED ON. I now believe (after talking to Maintenance and an Airbus Captain) I should have followed the second 'If' bullet. This would have prevented the overpressure situation on ENG 1 BLEED.
