I've always thought of it as "it's easier to make a working thing fast that it is to make a fast thing work" - which I'm sure I picked up somewhere....
The pattern here, if not the content, reminds me of "I do, we do, you do".
Kind of surprising to hear this on a website that largely talks about software.
Has any software ever been "right" the first time? I'm not sure.
The idea is to endeavor to be right, rather than purposefully cutting corners.
People don't appreciates how hard it is to do things right in your first attempt.
