changing from soft to hard tyres before race starts

Hi all
I have noticed a few times that just before the race starts the commentry states that a driver is changing to hard compound am I seeing things or is this possible.I thought the tyre you choose for the first stint is also your qually tyre????? This is after qually

Once preparation is locked no one is able to switch from softs to hards.

If you Qualify on Hards, you start on Hards.

If you Qualify on Softs, you start on Softs.

I think the commentry is just making the game more 'dynamic'.  The 'commentator' is assuming all cars are starting on softs so are changing to wets, hards, whatever for the race. 
Then again I might be wrong.

But what Ryan says is correct.

Thanks ryan and jake I will not worry about it but would be handy though
