Try debugging until you figure out how it works - you can enter code in home.tpl and see the values of the variables and understand why things are showing and not showing:

<p>Here is my debug code:<br />
main: {$main}<br />
current category: {$current_category.category}
</p>

{if $main eq "catalog" && $current_category.category eq ""}
<p>This should display only on the home page</p>
{else}
<p>This should display on other pages</p>
{/if}

Look at skin1/customer/home_main.tpl - it will give you an idea of what value to test for in $main for various pages.
