The USPS has missed most of they payments, not making a full one since 2010. The health benefits fund (the 50% one) was the only one that needed to be funded and much of that funding came from transfers from the other, overfunded, pension accounts.

Anyway, the point is moot, since the prefunding period is over and the payments are now on the permanent schedule. Because the Post Office couldn’t fully find the account, the fund is now running deficits and will be depleted in a decade.
