First off, I like to state that Michael Saylor sounded like a self-centred person there. Why wouldn't someone have a plan to pass their Bitcoin to a heir, friend or loved one if they knew they were going to die at a particular time like he stated? That's pure selfishness.
Most wealthy people have plans for their huge fortune, if they don't have children or relatives to inherit, they will also donate to charity and that is nothing new.
Michael Saylor took the risk to be at the forefront of the bitcoin investment movement, I don't think he would just buy and hold without any plan. I don't understand why people easily believe what that guy says and consider him an idol. But I hope people won't be surprised if MicroStrategy reports next year that they sold bitcoin while Michael Saylor still recommends people hold bitcoin

.
That would be unreasonable, imo, due to them profiting from said Bitcoin.
And Saylor would probably get all of his funds back into his own product, which would be MS.
