Neutered males can display erections and ejaculate just like intact males. They may mount in a display of dominance or can still mount to breed in the presence of an intact and receptive female. Correct the behavior immediately (even though no litters will come of it) and distract or separate him completely from the female until she is no longer in heat. Consider having your female spayed in the near future.

Some intact males will occasionally become intensely interested in a spayed female dog - this may happen because of some particular smell she has, but it isn't really known exactly what causes this to occur in some cases. The best option for now is to keep them separated, as you are currently doing. If there is no improvement in the situation in the next 2-3 weeks, you may want to consider neutering Buster to avoid having to deal with this constantly in the future.
