Interesting.
I suspect that the developer decided to be a bit weaselly in their wording of the console message (note the use of the word "may") since there could probably be a few conditions where this wouldn't be the case.
As I've mentioned in other threads, there's a lot of interesting stuff in the console logs, and there's a lot of dreck in there too, including mis-spellings and grammatically ambiguous messages. Much of what's in the console is only meant for the developers that wrote the code that issued the message, and those messages aren't necessarily any indication of anything wrong or amiss.
Unless you're having an issue, I wouldn't worry about it too much.
