Disagree. The sample arm was designed with spare gas for up to 3 sampling attempts, so they could go back and get more if they didn't have enough.
Since their sample-cup is filled to the brim and spilling over on the first attempt, they are choosing to stow the sample container, rather than go for another (redundant) attempt with an already-full sample container.
