In this help center article, there is some information about triage and help and improvement review queues.

• Triage – Stack Overflow only - 500 reputation. The primary goal of Triage is to quickly sort questions into groups: good as is, needs community editing, or should be closed/flagged.
• Help and improvement - Stack Overflow only - 2,000 reputation. This queue lets you edit questions that were flagged in Triage as needing community editing.

Since the aforementioned review queues are specific to Stack Overflow, I don't understand why the above quoted information exists in Ask Ubuntu help center.

Why does this information exist in Ask Ubuntu help center? Shouldn't it be removed?
