What do you mean when you say that \\b does not consume any character? Word boundary occurs at 0th position and 2nd position.

[admin]

It means even if \\b causes a match, you will not lose a character from the input in matching it. This is quite fundamental to regular expressions and is not possible to explain in a post. You should go through a book or a tutorial to understand what it means.
