its because at x1 position the spring is at its full elongation and friction is in opposite direction but as the spring is compressed to its extreme position at x2 the restoring force of spring at x2 will now try to elongate the spring and therefore the friction force wil act in opposite direction and hence there are two opposite directions of x1 and x2 i.e, x1-x2
