Not true, Singapore has something similar. They have GRCs (Group Representation Constituency) which consists of 3-5 seats and whoever gets > 50% (first past the post) of total votes from the GRC wins all the seats in the GRC.
That’s how the ruling party can win 90% of the seats in Parliament with only 60% of the popular vote.
EDIT: And how the Govt exploits the system to their advantage is to put one Cabinet member to head each GRC, with the assumption that people are much more likely to want to vote for Cabinet members than individual backbenchers.
