But once the whole sector has been erased (typically all cells are set to 1), you can write to any erased memory location once. Basically you can always turn a 1 into a 0, but not a 0 to a 1 without erasing. So indeed you can do the write because the area is pre-erased.

WebApr 1, 2024 · The flash_range_erase() function resets count bytes of flash (which needs to be a multiple of the sector size, 4096) beginning at address flash_offs, to 0xFF (all ones). This task appears to be the failure mode of flash when it wears out, as some of the bits won’t be flipped from zero back to one.
