Well, not necessarily.

Tier-2s should be given much more credit than they typically are in
write-ups like this.  When a customer is single homed to a tier-2 that has
multiple tier-1 upstreams, and uses a delegated netblock from the tier-2's
aggregations, that means one less ASN and one or more less routes in the
global table.

It's a Good Thing(tm).
