Why would I look at q.d._ssp.foo.com rather then q._ssp.d.foo.com or
_ssp.q.d.foo.com?

Because I established a TWO LEVEL rule as this the WORLD WIDE norm, and you can get to the other subdomains with juse TWO levels.

Also think about the global default record:

     *._SSP   0   TXT  ... your default policy ...

That allows you cover the entire company (zone), and for strict systems, a NOMAIL default will be ideal to combat fake subdomain abuse.

I understand it doesn't have to be that way, but I would like to know why there is a problem with that.

You guys are the DNS administrators. Tell me. My skin is very thick. If I am wrong with this method, explain how?
