My Answer below found the point's column value. I think perhaps you overlooked it.
I'll modify it to get the y value from the bottom most pixel.

How about
[rows, columns] = find(binaryImage);
[rightMostColumn, index1] = max(columns)
[bottomMostRow, index2] = max(rows)
deltaY = bottomMostRow - rows(index1); % Add 1 if you want.
Or to get the bounding box(es):
props = regionprops(binaryImage, 'BoundingBox');
Be aware that the bounding box is half a pixel outside the actual white pixels.
