Almond won seat 1, so Almond is struck from every ballot and the SAME twelve voters — all of them, including the five who already got nothing — count again for the second seat. That is the whole difference between block preferential voting and STV. STV would have spent the majority's ballots on the seat they already won; block preferential voting hands them back at full strength. Brioche now holds 7 of 12 first preferences outright and takes seat 2 in a single round. Final board: Almond and Brioche — both from the 7-voter (58%) majority. The 5-voter (42%) minority elects nobody. Run the same ballots under STV (bpv_bakery_stv_c4_b12.yaml) and the seats split 1-1.
