It's a natural mutation called polyembryony. It has nothing to do with how the plant was pollinated. It's just like when animals have twins, conjoined twins, etc. Polyembryony is common in plants and animals, and can happen by the division of the zygote after fertilization or by an adventitious embryo forming from the somatic tissue alongside the embryo. The reason twin plants aren't seen as often is because of PCD (programmed cell death), which kills off all but one monozygotic embryo to ensure survival of the one embryo.
