Here's a practical engineer's viewpoint:
Alfa has five gears, all the same except 1st; it's missing one syncro sector. It's either an upshift sector or a downshift sector. If it's missing the downshift sector, you can't get from 2nd DOWN to 1st. So it must be missing the UPSHIFT sector.
Interestingly, for the same thinking, they could have left out the DOWNSHIFT sector on 5th gear.
