  Sorry, I did not get it. How saving only vertexes is better than
having a polygon (made out of those vertexes)?

  Full geometry is required to be able to calculate label positions on
all scales. For small scales this could be a simple curved line
(calculated from polygon geometry), for large scales it could be a lot
of labels placed/scattered on the same polygon geometry and
approximating (simplifying) such polygon too much would decrease
number of labels placed or labels would be placed outside of an object
which is even worse.
