The single pole should be safe, that is why it is allowed. The double might help if for some obscure reason neutral became live. Or for testing and the like where it really does disconnect the appliance. You can not reliably test with things conected to neutral.

What’s a DP switch?
Double pole light switches, also known as a four-way switch, are two single pole switches put together. Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit.

Where do the red and black wires go on a light switch?
The black (hot) wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw. This wire is sometimes red. The green or bare copper (ground) wire, if the device has one, attaches to the green screw terminal on the switch or to the electrical box.
