I see three distinct possibilities (plus variations in between them):
1. He continues to win 8 every other year, on average, in which case, the remaining years on the contract will slowly decline. As he runs out of years, the AD has to decide whether to sign a new contract, or look for another option. That would no doubt depend on the circumstances. If they win 8, then 3, then 8, then 3, he might be replaced. If they win 10 then 7, then 10 then 7, the AD would presumably sign a new extension.
2. He wins 8+ virtually every year, in which case the chances of him being lured away by a P5 will increase exponentially. I presume that in return for the automatic extension, Albin was required to agree to a healthy buyout arrangement where Ohio will be compensated if he terminates early.
3. He rarely if ever wins 8, in which case the contract will run out in perhaps 4-5 years.
In none of these cases does the outcome look unreasonable or unfair to either party.
