It is 100% accurate. PCT application requires a local application first. OWCP filed provisional applications in US first and then filed for PCT within 12 months. You are right about USPTO provisional application is abandoned after 12 months. I'm not arguing otherwise. But once OWCP filed and published PCT applications they do not need USPTO application anymore as PCT covers 140+ countries including US. This is how international companies save money on patent filing because you have to spends loads of money to file for patents in each and every country. It is so simple!
