The schematic shows it operating directly on the A64's reset line, so it's rebooting the processor without directly affecting other parts. That _may_ make it a safer hard reset than just pulling the battery if your modem has the stock firmware, assuming there isn't a side effect of that reset causing a hard reset on the modem. I imagine it could make some low level development easier too.
The stock modem firmware is an embedded linux with has a filesystem mounted read-write, and if you're unlucky it can be corrupted if the modem isn't shut down cleanly before power is removed. The community firmware avoids this by not mounting the filesystem read-write.
