Go5g Plus: Question about multiple BOGO with BYOD

I have Go5g Plus 9+ line SOC I have: Line1-7 with a combination of BOGO/Free lines/3rd line on us. Line8-9: BOGO with ID260383 that was opened in June 2026 I plan to open Line10-11: BOGO with ID260677 and stack with BYOD on both lines Question: If I cancel the Line10-11 after I get the BYOD rebate. Will Line8-9 lose BOGO too due to 1 year no cancellation requirement of BOGO? Does the 1 year requirement to keep BOGO apply to only "number of lines active when BOGO was redeemed" or "exact lines that were active when BOGO was redeemed" ?
