Why doesn't jest --coverage show Uncovered Line?

Question

Unit testing

There is a method in the class

public updateRangeSliderValues(settings: ISettings): View {
  const isVertical = this.settings?.isVertical as boolean;

  if (settings.isTwoRunners) {
    this.range.setMarginFromBegin(this.rangeMarginFrom, isVertical);
    this.from.setMargin(this.thumbMarginFrom, settings);
    this.from.tooltip.setTooltipText(this.settings!.valueFrom);
  }
  this.range.setMarginFromEnd(this.rangeMarginTo, isVertical);
  this.to.setMargin(this.thumbMarginTo, settings);
  this.to.tooltip.setTooltipText(this.settings!.valueTo);
  return this;
}

When executing jest --coverage, there is not a single line of this code in the Uncovered Line column.
What does it mean this method does not need to be tested? Why?
