Conflicting description on getSnapshotBeforeUpdate section on the React.Component page

Page: https://reactjs.org/docs/react-component.html
Section: getSnapshotBeforeUpdate

The description after the code block reads

In the above examples, it is important to read the scrollHeight property in getSnapshotBeforeUpdate because there may be delays between “render” phase lifecycles (like render) and “commit” phase lifecycles (like getSnapshotBeforeUpdate and componentDidUpdate).

It is indicating that we should be reading the scrollHeight property in getSnapshotBeforeUpdate due to the delays between the "render" phase lifecycles and "commit" phases lifecycles. But getSnapshotBeforeUpdate is indicated as one of the "commit" phases lifecycle. Is that correct?

阅读 https://reactjs.org/docs/react-component.html 上 React.Component 页面中的 getSnapshotBeforeUpdate 部分，包括代码块及其下方带引号的说明。检查该描述是否正确区分了 render 阶段和 commit 阶段的生命周期，然后更新存在冲突的措辞，使生命周期时机明确无歧义。
