I think there is a O(N * M * 2N) solution for this problem. DP[i][j][p] = solution where we currently start at point (i, j) and the first i-bits of p belongs to the (j + 1)-column and the rest of the bits belongs to the j-column. And transitions are similar to the last solution. This utilizes the 2N different values of p and q more efficiently (since in the other solution, p cannot have zero bit before the last set bit, and q cannot have set bit after the row we currently stand in).
