In practice this happens for SF=11 and SF=12 and large enough bandwidths (you can do the maths).

It can also overcome frequency or sampling time drift on long messages particularly for small bandwidths.
 
 In practice it is difficult to make correct decodes if only one FFT bin is used to code one symbol (DE=0) therefore it is recommended to use a DE factor of 2 or more. With medium SNR DE=1 can still achieve good results.
