Idk I guess that's really up for you to decide. My opinion is that behavior seems very uhhh instinctual? Like if they were eating something that was running away from them I'm sure they would employ a similar tactic/behavior. Thing far away from me I need it closer. The logical steps to use a tool that would have 0 instinctual context seems leaps and bounds more "complex". I'm no animal/evolutionary scientist, just my opinion. It very well could be!
