Unfazed: I think you missed the subtle nuance ... the OHJ leads to a crosswind leg overhead the upwind runway numbers.
The crosswind circuit leg is further upwind from that, well beyond the runway numbers, the 500 foot aal point at which a departing a/c would make a 90 degree climbing turn on to crosswind. Anyone joining direct on the circuit crosswind leg has potentially another a/c climbing up underneath, with a high/low wing conflict making matters worse.
