I don't think the points race is as important as it might seem at first. I mean, you'd think losing 20 points to someone trying to lap you might be crucial, but all those points get you is the classification in the event, which are where the points for the overall Omnium are found. If the rider that finishes ahead of you in the standings has 1 point or 100 points more, they still only gain a single overall point on you. So is it really worth putting all that effort in to gaining a lap in the points race when it may leave you tired for the elimination (as the Polish girl proved)?
You dont get an easy ride whichever way you do it. If you dont get a lap, then you have to go for the sprints. Most people would find it harder to do 4 sprints than 1 longer effort needed to get a lap.
