Pillager outposts generate more substructures than before

Pillager outposts generate several substructures as I saw in every Java seed.

Steps (for 1.18):

1. Enter the seed 100.
2. Enter the command "/tp -391 105 1032" or "/tp -983 98 824"
3. You will see the pillager outpost generating several substructures.

Expected result: Pillager outposts should generate substructures normally.

Observed result: Pillager outposts generate several substructures.
