Ya that website is full of errors. Both 'Grand Nain' and 'Dwarf Cavendish' have more or less persistent male flowers, though 'Grand Nain' flowers will sometimes shed though not completely. It is also different from 'Williams' which has a completely dehiscent male flowers.

Both Bluggoe types and 'Ice Cream' are ABB, but that does not mean they are closely related. ABB just means they are triploids with one set of chromosomes from some type of M. acuminata and two from some type of M. balbisiana, but the exact types and how they were put together are not part of that code and so you can have two ABB types that have completely different evolutionary histories.
