Excerpt length varies in featured content

Hi Sakin It seems that the excerpt length varies in the featured content (in column 3) (http://wordpress.lounge-dj.dk/). I've set the "Excerpt"-option to 45 words. In column 1 and 2 there are 45 words, but in column 3 there are a few more, which adds an extra line. This makes the layout seem a bit off. Is that normal?
