The (77) defines transaction's final state σ′ where both selfdestructed and empty-but-touched accounts are deleted. This is not how this is implemented in practice.
What YP suggests is the following workflow:
for tx in transactions:
execute(state, tx)
delete_selfdestructed(state)
delete_empty_but_touched(state)
apply_coinbase_reward()
apply_withdrawals()
Practical implementations are done as the following:
for tx in transactions:
execute(state, tx)
delete_selfdestructed(state)
apply_coinbase_reward()
apply_withdrawals()
delete_empty_but_touched(state)
The difference is subtle: in case we apply 0 block reward or 0 withdrawal to an empty account this account will be deleted.
