Why are these triacs connected to the neutral instead of the line?

Hello friends, first of all excuse my English I am from Spain and I am not a native English speaker, this main board is from a dolce gusto coffee maker and what intrigues me is to know why these two triacs are connected to the neutral line instead of the live line because as far as I know the live line is the one that carries the current.
Here I made a little video showing the board, thank you very much.

Both conductors, live and neutral carry the same current.
Electrically speaking, there is no difference in which line the control is in.
If this is a two conductor fed machine, i.e. no GND conductor and is double insulated appliance, it really makes no difference.
Hint AC is Alternating Current, IOW the current alternates direction in each supply conductor 50 (or 60) times/sec

Holla Marcos,
bienvenido a Electronicspoint.

Mains outlets in Spain do not have a dedicated neutral and live socket. You can insert the plug any way you want, thus swapping neutral and live.
For safety reasons always assume that either of the two wires may be live, depending on the orientation of the plug in the mains outlet.
