Yes, it's a 4 stroke, she fires every other time the piston comes up, BUT, the spark goes off EVERY time the piston comes up.
It would be more expensive and complicated to run the ignition off the camshaft, (1/2 rpm of crank) much cheaper and simpler to run the ignition off the crank/flywheel, so every other spark is 'wasted'.
One goes off at the top of the compression stroke, (squeeze) one goes off at the top of the exhaust stroke. (blow)
