Party Rebuy Tournament Question

[josh1122]

The rules for rebuying in the re-buy window state that one cannot re-buy until their chipcount is less than what they started with (t1000). Yet every now and then in the chat window I see someone with more than that rebuying and increasing their already large stack. And I am not mistaking this for the add-on. This occurs during the re-buy period and not the add-on period. Am I missing something simple? What gives?
