Towing with omnistomp

Hello

What happen if I tow moving a side with omnistomp ? For example Bomb is IN FRONT of me (I can push it just by moving 1 forward), I use omnistomp by moving 2 times left, 1 time for move and the second time for towing. Does the bomb go behind me (bomb is moving 4 spaces (3 bottom and 1 left), in front of me (bomb is moving 1 space to the left), or at my right (bomb move 1 space to the bottom) ? (I think we can't have nothing because we can tow with any adjacent space)

To be clear, here is a schema with Mech facing top of this page :

From this X B X X M X

By moving to the left, which one do we get : 1 - B X X M X X

2 - X X X M B X

3 - X X X M X X B X X
