The thread is about something that checks brackets the same way as the built-in bracket checker, which I was reading as being Ctrl-H. If the 2 colors for the brackets means that it's matching the 4 brackets without warning of errors, then it's behaving like mIRC, where Ctrl+H doesn't warn of an error, but the end bracket of that internal pair is ignored when the if() condition is $false, but recognized when $true.
