Here's why:

* Telophase I: After the separation of homologous chromosomes in anaphase I, the cell begins to divide. In telophase I, the chromosomes are at the poles of the cell, and the nuclear membrane reforms around each set of chromosomes, effectively creating two nuclei within the cell.

* Telophase II: After the separation of sister chromatids in anaphase II, the cell again divides. In telophase II, the chromosomes are at the poles of the cell, and the nuclear membrane reforms around each set of chromosomes, creating four nuclei in total.

Remember that meiosis involves two rounds of cell division: meiosis I and meiosis II. The nuclear membrane reforms in both rounds, marking the completion of each division and the formation of new nuclei.
