Well, that's the thing ...
This is only time we have sent-off an entire boar at over a year old & he stunk like a stinky boar for several months before his last trip. So we were concerned that there would automatically be boar-taint (not that we could smell anything when we divided-up the rough cuts though).
So, could it be that he didn't have it because he'd never been with the girls, even though his "eu de porcine" was overwhelming?
