DQL: Am I using vars correctly?

Looks like you have found a logical bug in the query process. But the “right” way of doing it is.

{
  A as var(func: has(Worker.abilities))@cascade {
    Worker.abilities @filter(uid_in(Ability.knowledge, 0x2e0))
  }
      
  results(func: uid(A)) {
    uid
  }    
}
