The margins are unrelated to the position of the left border of the text block.

ConTeXt use the value from “backspace” for the inner (left) space and the “cutspace”
value (normaly calculated by ConTeXt when you set a value for “backspace” and “width”)
for the space on the outer (right) side.

These are the three values for the horizontal dimensions:

| backspace | width | cutspace |
