His legs not broken

The soldiers break the legs of the two beside him and stop at his body.

In plain words

The soldiers break the legs of the two men crucified beside him and, finding him already dead, leave his unbroken. John ties it to the Passover rule that no bone be broken: men running a routine procedure halt at the one body where that rule was written.

The mechanism

THE SPEC PAID BY MEN RUNNING A PROCEDURE — an execution crew halts at the one body where halting was written down as a lamb specification

Scripture
