[css-flexbox] rationale for definite size conditions

https://drafts.csswg.org/css-flexbox/#definite-sizes

For the second case, why is it a condition that the flex container has
a definite size? In what way does that simplify things relative to
just the flex item having a definite flex basis?

thanks!
