How exactly is this a plot hole? When she fought her children she did so in her Ten Tails form. When the brothers used the jutsu it likely separated her into her body and her chakra, just as it did for Naruto and Sasuke. The key difference here is that Hagoromo had already divided her chakra before, so when Naruto and Sasuke performed the Jutsu, the chakra came out in the form of the nine Tailed Beasts. When Hagoromo and Hamura did it they created the Gedo Mazo and sealed it in the moon. At that point in time they sealed the chakra within Hagoromo.
