One possible reason for this is that, if a remote branch (e.g. origin/myBranch) still exists, then git checkout myBranchwill succeed as an alternative to git checkout -b myBranch origin/myBranch. This is intended as a convenience for the common case of checkout out a remote branch for the first time, creating an identically named local tracking branch.
一个可能的原因是，如果远程分支（例如origin/myBranch）仍然存在，那么git checkout myBranch作为git checkout -b myBranch origin/myBranch. 这是为了方便第一次检出远程分支的常见情况，创建一个同名的本地跟踪分支。
There are other possibilities, too, depending on what exactly you are using for completion, but that's one of the first things I'd check. If you run git branch -a, and there is an origin/myBranchlisted (or one for a remote other than origin, if you have such), then that's a likely culprit.
还有其他可能性，具体取决于您用于完成的确切内容，但这是我要检查的第一件事。如果您运行git branch -a，并且有一个origin/myBranch列出的（或一个用于远程以外的origin，如果您有这样的），那么这可能是罪魁祸首。

Posting this as its own answer since it's a one-line fix, but if you vote be sure to vote for @twalberg's answer above.
将此作为自己的答案发布，因为它是一个单行修复程序，但如果您投票，请务必投票支持上面@twalberg 的答案。
@twalberg's suggestion to git branch -aled me on the right track; my coworker suggested git fetch --prune --allto prune all the dead branches from all the remotes, which is useful when working with lots of devs with lots of forks.
@twalberg 的建议让git branch -a我走上正轨；我的同事建议git fetch --prune --all修剪所有遥控器上的所有死分支，这在与许多具有大量分支的开发人员一起工作时非常有用。
