Maybe they agreed, or maybe it was randomly selected. From the rulebook:

1.5 Determining Wrestling Order
Immediately after the weigh-in for a dual meet or multiple dual meets conducted
on the same day, coaches may mutually agree to determine the order of matches
to be wrestled, allowing for a particular weight class to be featured. Once the first
weight class is established, subsequent matches will continue in the traditional
sequence of increasing weight class.
If coaches cannot agree on the wrestling order, a random draw shall be
conducted to determine which weight class will be wrestled first
