I also believe I had heard from my teacher a different answer regarding this. It is that this is only meant to be when every single degree is in its proper place because then the measure of the lowest degree in the higher Olam is greater than everything below it. However, when Olam Beria rises to Olam Atzilut Beria returns to being in the degree of Atzilut itself and requires the same amount of space as if it is Atzilut in itself, etc. similarly. Hence, when Yetzira rises to Nukva de Atzilut’s place she returns to being in her merit. Then the first four Sefirot of Yetzira require the same measure of space as the Nekeva of Atzilut, whose measure is also four Sefirot de Atzilut.
