Thanks for correcting the (obviously) incorrect statement.

Genetics is much more nuanced than that high school biology understanding.

“you get offspring that are infertile”

That is not true. The offspring can still reproduce.

Hybrid incompatibility can be driven by the different locations of alleles. My premise was that sterilization is a designed feature, therefore, these lines can be designed with dislocated allele. They would need to maintain 2 different lines, then when they want to send eggs to the third party producer, they'll take some from each line, breed them, and send those infertile eggs to the producer. Hence the single generation mentioned in the PR, and hence the added security.

As far a the notion that "breeding won’t all have the same desired characteristics of the parents though", that too is nuanced. You might be right if the the phenotype wasn't from a dominant genotype. For instance, if one genotype was "AA" and the other line was "aa" You would have all genotypes being heterozygous (Aa). If that genotype translates to the desired phenotype, then 100% all offspring would have the desired trait. This is just a simplified example.
