adding conditionals to load script

I have added conditional tags to javascript loading function

if (!is_admin()) add_action( 'wp_print_scripts', 'theme_javascript_home' );
function theme_javascript_home( ) {
wp_reset_query();
if (is_home()) {
wp_enqueue_script( 'script1', get_bloginfo('template_directory').'/js/script1.js', array( 'jquery' ) );
}
}
if (!is_admin()) add_action( 'wp_print_scripts', 'theme_javascript_single' );
function theme_javascript_single( ) {
if (is_single()) {
wp_enqueue_script( 'script2', get_bloginfo('template_directory').'/js/script2.js');
}
}
remove_action('wp_head', 'wp_print_scripts');
add_action('wp_footer', 'wp_print_scripts', 5);

Why I did it? So script1 (home page) will be loaded only when browsing home page. As many visitors get to the single page first and it takes a few clicks untill they get to the home page. It doesn’t load jquery, which I use on the home page only, untill visitor gets to the home page.

Firebug shows difference.

Would someone comment on this practice. Is it good ?
Also you can see that using function loads javascript in the footer.
Thank you
