So just adding more about it, it seems that the sex consists of 4 parts, A-alpha, A-beta, B-alpha, B-beta. To be compatible it has to have differences in (A-alpha OR A-beta) AND (B-Alpha OR B-beta). I can't help but think that this complex system has to have evolved to very precisely control inbreeding rates.

In plants, your genetic siblings are in many cases growing very physically close to you - especially if the seed dispersal mechanism isn't great. That makes mechanisms to reduce inbreeding even more important.
