My friend says his payment cheque (thru employer) debited by USCIS...!!! What does it mean?

I and my friend had applied for H1B this year and he got an update from his employer that payment cheque was debited by USCIS…!!! Means, his number was picked in lottery. We both are applied in regular and as per the latest update, premium processing will start on 12th may, 2016.

So, would like to know whether my friend is selected in lottery? If Yes, should I ask my employer for the same?

If his check was cashed, then he made through the lottery.
