Ambiguity in the explanation: Figure 1 and Table 1.

[ahmadmobeen]

In the paper the Table 1 Bottom layers should be addressed as Top Layers and vice versa. Because, the all layers except input layers are being updated and X0 is the input layer and is written under the column of bottom layers so maybe I think either the column names should be switched.
I make above understanding based on the assumption that the top layers update the bottom layers.
If I misunderstood please someone explain this and rectify me.

Thanks
