Why is the indentation of document.write() methods like that after while()?

The first document.write() is aligned with while() but the next document.write() is not indented and so it aligns with the do loop itself. Why is that? Since both document.write methods are outside of the code block and while condition argument I would think they should both be aligned with the do loop since they are not nested.

My guess is that it ws unintentional. The editor probably auto-indented the first one, mistaking the kind of loop.

The editor misunderstanding can probably be avoided by putting a semicolon at the end of the "while" expression, which I would consider a "best practice" anyway.
