Start faults on A320 with CFM

Hello
I’ve been operating on Airbus with CFM almost a year now . Coming from A320 with IAE and having experienced a few start faults in actual operations ( and simulator ) I want to clarify some differences I saw in the FCOM on this issue. Here is the FCOM extract I want to clarify
On the ground (auto start) : L2 If the engine does not start, the FADEC can attempt an additional engine restart. After any start attempt that is not successful, a dry crank phase automatically occurs. The ECAM displays the following messages:
L1 AUTO CRANK IN PROGRESS
NEW START IN PROGRESS
-When the final dry cranking process is finished: ENG MASTER (AFFECTED)..............................................OFF
It seems to me that the FCOM suggests that the FADEC will attempt several auto-cranks followed each time by a start attempt . This is definitely not how an IAE engine would behave ( IAE only displays and performes 1 Dry crank . There is no display of “New start in progress” ecam , nor have I seen one been attempted even without the ECAM saying so )

If you have seen it can you please comment on your experience?
