Cytokinesis in plant cells

I was wondering if anyone could explain the following:

"if the dividing cell wall were formed before the daughter cells separated they would immediately undergo osmotic lysis"

My textbook doesn't really explain why they would undergo osmotic lysis.

Probabily because the cell wall can only resist pressure for a particular cell size, if 2 cells are in the same cell wall that means double the size of a normal cell so the increases in volume can not be stabilised, cell wall breaks so does plasma membrane. I am not sure of my answer but that's what I could think of.

Edit: in case it is not clear, the increase in volume due to osmosin of water into the cell due to differences in water potential.
