That's the EBU regulation. The ACBL regulation is "put down the stop card, put down your bid card, pick up the stop card". Nonetheless some people leave the stop card out, and some people think that they can't bid until the stop card is removed. But most people just ignore the stop card and the fact that RHO jumped and bid in their normal tempo. Unless they have something to think about, in which case they "hesitate". There doesn't seem to be a way, short of PPs, to get them to stop that.
