Not quite—  You generate a normal block, then use your trust account to mine a trusted block right after it (especially easy since it's a minimal difficulty computation).  If someone else had beat you to the punch on the normal block it doesn't matter— the chain with the trusted block is the longest one.  So while the trusted block itself costs you coins it gives you a veto over the identity of the generator of the prior block.

It's even super extra special if you're the operator of this system— because the fee in the trusted blocks goes to to operator, so once he's extracted out the few hundred thousand in surplus coin those pre-mined accounts were equipped with he can simply recycle their fee and maintain them (and their ability to control the winning chain, and thus who the normal block coin goes to) indefinitely.
