Redstonetorch does not activate when given a 2 tick pulse

I placed a redstonetorch on the side of a powered block (which creates a 1-tick pulse) and I expected both redstonetorches on the top to give a pulse
But instead only 1 of the redstonetorches gave a signal. (2 redstoneticks) The other torch did not give a pulse.

How to reproduce:
1. Build the setup from the picture.
2. Make sure that the lever is activated
3. Place the redstonetorch I am pointing at in the picture at the side of the block with the lever.
4. Notice that only 1 of the torches gives a signal.

Suggestion:
Making redstonetorches so that
a 1 tick pulse will output a 1 tick pulse
a 2 tick pulse will output a 2 tick pulse
a 3 tick pulse will output a 3 tick pulse
etc.
