There's multiple differences in the government systems in the countries of Jordan and Kuwait on one side, and the United Arab Emirates and Oman on the other side.
Jordan and Kuwait are both countries that have parliamentary monarchies. They have a Prime Minister that is the head of the country, and also there's a multiparty system, so the people can vote for their leader.
The United Arab Emirates and Oman, on the other hand, are countries that have constitutional monarchies. The monarch is leading the country, and it is not the people that have their say in the choice by voting, instead, it is the only the high class representatives of the society that vote for who will lead the country.
The main way in which the separation of powers guards against tyranny is by making it impossible for any single branch to become too powerful, since each branch "checks and balances" the others out when it comes to making and enforcing legislation.
