Thanks.  That matches my guess.

Wouldn't it be useful to mention it in CodingGuidelines?

A danger is that the declaration (that yes, this really is initialised
before use) becomes invalid during further changes, so it's best if
everybody concerned understands the convention.

Obviously if it's a commonly understood and used convention then it's
just as well not to have it in CodingGuidelines, but I'm not convinced
that this one is, though (having noticed it) the intention isn't hard to
grok.
