OMSCS能用来申请OPT Extension吗？

如图，在另一个帖子里我看到：

“并不是只有学位项目才有opt，一些短期的certificate项目也提供一年的opt。
可以这样操作：用完一年的opt之后，再用online CS MS申请两年的STEM OPT extension”

（instant.1point3acres.cn）

我后来查了一下，貌似这样确实行得通：

To qualify for the 24-month STEM OPT extension, you must:

• Be in F-1 status
• Be currently working in a period of post-completion OPT
• Have a bachelor’s degree or higher degree in an eligible STEM field
  

You may be eligible use a prior STEM degree earned in the U.S. for this requirement; to use a prior STEM degree, you must:
Have received your most recent degree (which does not need to be STEM-related) from a currently accredited Student and Exchange Visitor Program (SEVP)-certified school in the U.S.
Have received your prior, qualifying STEM degree in the U.S. within 10 years of applying for the STEM OPT extension.
The qualifying STEM degree must be on the Department of Homeland Security’s STEM Designated Degree Program List at the time you submit your STEM OPT extension application (rather than at the time you received the degree).

请问是否有人这样做过 证明确实行得通呢？

补充内容 (2019-6-20 10:42):
很多人混淆了OPT和OPT extension，所以补充说明一下：OPT和OPT extension是分开申请的。截图中说的意思是：如果你读的是文科专业或certificate program，那么本来只有一年OPT，但可以用OMSCS申请OPT extension。
