I think  that "Yo ta hununai thiyo. Bhayo." It happened at wrong for Maoists in a time that fit their mouth. I am  not sure about their throat size. Like reptiles, they will be able to swallow it very slowly, because Maoists are not mammals, so they they have seperate NALI to pass air to lung. As it approaches to their stomach, they will swallow stone so that they can crush Ram Hari Shrestha's body as reptiles do after consuming a large prey. It is just a matter of time. Then, the reptile is ready for another prey.
