Homepage ‘numberposts’ with correct pagination and offsetting on latter pages

I’ve been trying to get the 2 latest posts on my homepage; with the pagination resorting back to 10 posts per page once ‘next’ is clicked to get to page/2/ etc.

//detect the set number of posts per page
		$ppp = get_option('posts_per_page');

		// first page 2 posts
		if (!is_paged()) {
		    $posts = get_posts('numberposts=2');
		// second page with offset
		} elseif($paged == 2) {
		    $posts = get_posts('offset=2');
		// all other pages with settings from backend
		} else {
			$offset = $ppp*($paged-2)+2;
		    $posts = get_posts('offset='.$offset);
		}

This is the code i’ve been using, which makes sense, however, only 1 post appears on page 2 with the rest not showing :S I’ve also noticed that as i decrease posts_per_page, via the setting in wp-admin under reading, more posts appear. Once i get to 2 posts per page, they all show up. Bizarre :S
I can’t for the life of me figure out what’s going wrong! ??

I got the code from; WP engineer – Correct pagination with get_posts
