retail entitlement offer eligibility

Hi guys, I have a question about the eligibility for the retail entitlement offer. The announcement of 17 June says:

"The record date of the entitlement is 18 June 2009"

but also that:

"For the purposes of determining entitlements to the Entitlement offer, the Group will ignore changes in security holdings which occur after the commencement of the trading halt on Monday, 15 June 2009"

I don't get the second bit, does that mean that if you bought shares after the 15th June then you aren't eligible? If that was the case then that essentially means that the record date would be the 15th, so I don't understand...
