目前，天蓝色的devops就是这样设计的. Devops只能同时进行一对一的分支合并.release分支不能同时合并到master分支和develop分支中.

At present, azure devops is designed like this. Devops can only be one-to-one branch merge at the same time.The release branch cannot be merged into the master branch and into the develop branch at the same time.

发行完成后，发行分支将合并到母版中 并开发，以确保 发行分支不会因新开发而意外丢失.

When the release is finished, the release branch is merged into master and into develop too, to make sure that any changes made in the release branch aren’t accidentally lost by new development.

在git flow中描述的此功能无法在天蓝色的Devops中实现.

This feature described in git flow cannot be implemented in azure Devops.

因此，您的理解是正确的，尽管这可能有点不方便，但是您可以通过您的方法手动进行操作.

So, your understanding is correct, you can do it manually by your method, although this may be a bit inconvenient.
