depth-wise separable convolution code question

Lines 78 to 85 in 8260768

 self.shared_block = nn.Sequential( 
     in_conv1d, 
     nn.PReLU(), 
     conv_norm(hid_chan), 
     depth_conv1d, 
     nn.PReLU(), 
     conv_norm(hid_chan), 
 ) 

In this code, the order of operation is point-wise -> depth-wise convolution
However, in my knowledge, the order of the operation is depth-wise -> point-wise convolution.
May I ask you the reason that the code was made like that?

Oh, the paper writer made the model like that
I didn't check before to ask

• I read the code wrong
  I'm sorry
