The highlighted portion is simply not accurate. Consider the following scenario:
A president breaks laws--This does not change the law, the law still exists, it was simply broken. The president's party has a majority in either the House or the Senate and chooses to turn a blind eye to the president breaking laws; this results in a failure to bring impeachment charges against the president, or a failure to convict on impeachment charges brought by the house.
No law was changed yet the president broke a law without consequence. Lather, rinse, repeat. More laws broken, no consequence, and no laws changed.
QED.
As I said before: Your logic is seriously lacking.
