An axis organizes movement without fixing it
Imagine the slot as a narrow, imaginary path where the follower moves mainly between two end areas. These end areas are not exact footprints. They give you a sense of the space where a path begins and where it can lead. Turns and small sideways movements fit within it as long as the overall direction remains clear.
For how you use the space in West Coast Swing, this means you need an elongated area for movement, but not a permanently reserved strip. The slot belongs to you as a couple and takes shape through your dance. It does not have to run parallel to a particular wall or keep the same orientation for every song.
The axis describes a path above all, not a direction you are facing. You can turn your upper body in a different direction as a figure unfolds without automatically changing paths. Conversely, a side step can take you off the path even while you continue facing your partner.
This distinction is especially helpful when learning: not every body turn changes the slot. But a genuinely new direction of movement needs to be clear to both of you. That way, you can stay oriented without making your dancing look like it is on rails.
