If you read the above carefully, please note the words _also_ and _initial_.
I.e. -k will cause _another_ signal to be sent, iff the first doesn't terminate the command.

Hopefully this example with all pertinent options explains things.
I.e. the first signal sent after 1s is ignored,
and the second kill signal sent after another 2s forcefully kills the command.

  $ date +%s; timeout -k 2s -s0 1s sleep inf; date +%s
