It is possible to be a "Tier Two" provider and use communities &  
route-maps to look like a Tier One.  You purchase transit, therefore  
are not tier one, but are unreachable through your transit unless the  
end point is a downstream of your transit provider.

Architecturally, those are identical situations.  Different  
commercial agreements, though.

P.S. How much you wanna bet some of the "tier ones" are paying other  
"tier ones" more for fiber or colo or something than the "tier twos".
