Yes, Marcio. It´s poetic licence, and a way of drawing interest (in music, poetry etc they often do that.)
As for the question, I think it´s something like the one in the following discussion.http://linguaphiles.livejournal.com/5947241.html
My suit is black.
I'm wearing a black suit.
(Sound like, to me, a verb phrase to modify a noun) Instead of "I´m wearing a suit that is black."
