Commercial levels are on the first four floors. Having the windows face each other on these floors are not a concern as they are commercial spaces (and don’t need privacy) and in most cases the commercial unit spans a large swath of floor area so those windows that look on to each other are most likely belong to the same commercial unit.
As for the residential levels, the windows that face straight into another unit are vision glass block to provide some privacy while still allow light. The courtyard units are in a more unique situation where they all face each other in all directions in a narrow canyon-like space, so there is a given that those units will have much less privacy and daylight.
