But the input always makes the entire column become active, because it is
connected to the column and not individual cells in the column, right? That
seems contradictory.

Does the entire column being activated by the input not imply the same
consequences as bursting?

There is a difference between an "active column" and an "active cell". Spatial
Pooling provides a stream of active columns representing spatial information.
The TM algorithm operates within that space. It only activates cells that are
within active columns. You'll never see a cell activate in HTM outside of an
active column. This means that the proximal input is the ultimate driver of
cell activations.
I don't know the exact neuroscience of how proximal input is shared by the
cells within a column.
I explain the two conditions that cells become active at
