What does 'roll' mean in the Random Rotator?

From the source:

FRotator UKismetMathLibrary::RandomRotator(bool bRoll)
{
	FRotator RRot;
	RRot.Yaw = FMath::FRand() * 360.f;
	RRot.Pitch = FMath::FRand() * 360.f;

	if (bRoll)
	{
		RRot.Roll = FMath::FRand() * 360.f;
	}
	else
	{
		RRot.Roll = 0;
	}
	return RRot;
}

seems like taking a random pitch and yaw is enough to get a random rotator, but you can opt to do an extra randomness on the roll. In this case it’s really confusing that they use the X instead of Roll here (since in x,y,z x is the first, while it’s last in pitch, yaw, and roll). Also I still don’t know what having a random roll adds to the already random rotator.
