shouldn't the masked softmax loss output be 
[2.30126,2.30126,0] ? 
because first sequence has 4 elements each equals to 2.30126,
second sequence has 2 elements each equals to 2.30126, 
dividing by their valid length means 2.30126*4/4=2.30126 and 2.30126*2/2=2.30126.
it seems to me it's divided by 4 which includes the padding length, makes no sense!
