It's much less "moment's notice" than it is planned personal/vacation days, or injuries that require a decent amount of healing time. It's better to have the production still fully staffed than run into a problem because, for example, the standby was supposed to do the whole weekend but got food poisoning and now we're in a jam...
It also makes financial sense to have one person be an insurance policy for several companies rather than hiring an additional swing/standby for each company.
