What guarantees here that the reverse voltage is only (mainly) at the diode
and not at the LED? They are both in reverse during the reverse cycle. 

The purpose of the anti-parallel diode is to guarantee that the reverse
voltage at the LED remains low. You can use both diodes (series and
anti-parallel)...
