Another example of this would be if there are three candidates X,Y,Z. Suppose Alice strongly prefers X and Bob strongly prefers Y. Rather than each of Alice and Bob allocating 100 points to their preferred candidate, they can each allocate 50 points to X and 50 points to Y. The net effect is that they have multiplied each of their voting power by sqrt(2).

I don't like any voting system that incentivizes group collusion. A much fairer system would be some form of random ballot: everyone gets to allocate some number of votes, and then a random vote gets picked to select the winner. This type of system is especially good for situations where there are many winners (eg the Congress), since it allows for even small parties (eg the Green party) to get proportionate representation.
