If you had complete control over a voting machine, it wouldn't make any sense to try to lower turnout or confuse anyone- you'd want people to vote and leave without having noticed anything, so you could change their vote. The result here is that the voting machine was taken out of duty and will be investigated. If the strategy was to make the error so outlandish that nobody would believe it was happening, the strategy has failed. Since it's pretty obvious that this would be the outcome, it's not a good strategy, and is therefore not likely to have been enacted.
