Because the init script is called only once during boot, whereas new
devices may also appear later. As an example, in the case that Vincent
Bernat brought up, the lvm2 init script runs after the first hard disk
is crypto-unlocked and available, but does not run again (obviously)
after the second hard disk becomes crypto-unlocked (with a key file that
is stored on the first one).

systemd in general does things based on events and whenever appropriate,
so this generator is required to make things work.

I hope this clarifies, if not, please let me know. Thanks.
