Question about State Farm Visa agent signup bonus.

The State Farm / US Bank Visa offers 3% cash back on the first $4000 spend annually. They also offer a bonus: signup through your insurance agent, and get an extra 2% cash back for the first year.

On their website it says: 

3% cash back on insurance premium payments, up to $4,000 spent annually

Special offer:  By applying directly through a State Farm agent, earn up to 5% cash back on insurance premium payments for the first year.

in my statement it shows:

3% Cash Insurance up to $4,000 / 1% After   $x.xx
2% Cash Agent Insurance Offer   $x.xx

So it seems like the 1yr agent bonus is a 2% add-on.  

However, the agent bonus is not mentioned anywhere in the T&C paperwork, or any other docs I received with the card that I could find.

QUESTION: does anyone know if the 2% agent bonus continues to apply after the $4k annual limit is reached.  

Asking because I will hit the 4k limit soon, and wondering if I will get 3% or only 1% until my card anniversary.
