regex at word boundaryby mikeraz (Friar)

mikeraz has asked for the wisdom of the Perl Monks concerning the following question:
I'm writing a bit to look for palindromes. To search for those with embedded whitespace, like "God dog" I started with this regex:
But it matches any line. For instance:
Being able to script this in Perl gives a lot more flexibility, and is arguably easier to use and extend.I'm blind as to where the $2 match is occuring in those two lines. There is no word ending in b on the first line. There is no word ending in i on the second.
What is the problem with my perception of the regex?
update: OP used <pre> instead of <code> tags. This confused the issue for the first few replies. Question was really and completely addressed by japhy - I was asking for the smack upside the head to clear out temporary blindness.
