Not at all the same thing. A "four-sided triangle" by definition, is not a triangle.
Your god is 'all-powerful', yet cannot make a rock so big that it cannot be moved. Contradiction, therefore god does not exist.
Omnipotence means that God has infinite power and and is able to do anything that is logically possible.
God cannot do something that is logically impossible, because such a task is meaningless. Making a square circle or a tall short person, like your two proposals, are examples of things that are not logically possible because they are in themselves contradictions.
God is perfection of all good things and able to do anything that is doable. A contradiction does not fall into that category of doable things.
