The crossing changes the foot sequence, not the direction of travel
The Backward Lock is a progressive figure: your feet briefly come into a tight crossed position while your body continues moving backward. The crossing is a weight-bearing step, not a tap on the floor. If your weight stays on the standing leg, you won't have a free foot to continue with. You might get into position, but you wouldn't dance through the figure.
For this guide, the backward-moving role starts with the left foot. Its sequence is: left back, right back and slightly to the side, left crossing in front of the right, right back. The opposite pathway starts with the right foot forward. This description of the roles is independent of who leads. The starting foot depends on the chosen variation and the connection; a mirrored exercise requires swapping the foot directions throughout.
The slight sideways opening on the second step creates space for the crossing. It is not a large side step and not an invitation to twist your upper body. Your dance partner stays slightly offset rather than toe to toe. To see how it fits into the repertoire, check out the overview of Quickstep figures for beginners. You'll also encounter the idea that starting foot and direction of travel belong together when coordinating the step paths in the Foxtrot Right Turn; however, you don't apply its foot sequence to this Lock.
