The original subdomain is currently pointed away from the normal server
I've been placing it inside the root .htaccess of the domain, not the subdomain.
If I'm reading this right, requests for the subdomain currently get sent to a completely different server. That means they will never see directives in the main domain's server-- regardless of directory-- because they don't get there until after they've been redirected.
Who's doing the pointing? Is it at the DNS level, or something that the host has cobbled together?
Elsewhere: If you're throwing away the last part of the URL, you don't need to capture it-- or even look at it, unless you need to make sure it does exist.
