the description of SSAM is inconsistent with the code

[jiayu-Zou]

theoretical code： att = torch.softmax(torch.mul(mxpool, avgpool), 1) fusion = attt * avgpool + attt * mxpool

actual code : att = torch.softmax(torch.mul(mxpool, avgpool), 1) attt1 = att[:, 0, :, :].unsqueeze(1) attt2 = att[:, 1, :, :].unsqueeze(1) fusion = attt1 * avgpool + attt2 * mxpool

why？
