[問題] 改成這樣有什麼好處

重構中有招叫做Introduce Assertion
網路上找到的例子是把：
double getExpenseLimit() {
// should have either expense limit or a primary project
return (_expenseLimit != NULL_EXPENSE) ?
_expenseLimit:
_primaryProject.getMemberExpenseLimit();
}
變成：
double getExpenseLimit() {
Assert.isTrue (_expenseLimit != NULL_EXPENSE || _primaryProject != null);
return (_expenseLimit != NULL_EXPENSE) ?
_expenseLimit:
_primaryProject.getMemberExpenseLimit();
}
為何改良後還是用 _expenseLimit != NULL_EXPENSE 做為判斷？
還是例子有誤呢？
好處是不必使用註解嗎？
