From your chart it looks to me like the approach could begin inside MEXUN as long at it was not later than ML627 which is the FAF. Not a huge difference but I've received these direct to FAF RNAV-P clearances in Europe before. And sometimes I've gotten vectors that seem to closely mimic the published side approach transitions.
From ATSB website these guys were 15 nm south though and perhaps vectored for the long final.
