What is the origin of the idiom "in the same breath" and when to use it?

The origin of the idiom "in the same breath" can be traced back to ancient Greek rhetoric and literary devices. In Greek rhetoric, there was a technique called "symploke" which involved connecting contrasting or contradictory ideas or statements in quick succession. This technique was used to create emphasis, surprise, or irony in speech or writing. It is now commonly used in conversations, debates, or discussions where someone makes contrasting or contradictory remarks or expresses conflicting thoughts or opinions in a short span of time.
