This video is a chance encounter, not a feeding or a bug fight.

This Phidippus audax caught a Trochosa wolf spider on a log that was swarming with them. Still surrounded and with its fangs occupied, it nervously kept an eye on the other spiders around it while it ate.

In this segment it is looking at a Trochosa with its back turned, when another slightly to the right approaches and catches its attention. Its reaction looked strategic to me, slowly sidestepping until it was closer to being behind the first wolf spider, ensuring that the interloper would be more interested in it than the audax. Maybe not. But I think the body language looks deliberate.
