Faith, you badly misunderstand both diagrams.
The first shows how local formations relate to the geological timescale. The second is an idealisation which does not even attempt to show the complexities of the actual situation.
The geological timescale is not built on world-wide strata. It was built by painstaking work correlating the local strata of different localities, primarily through geometric relationships. Applying the original version , developed in Europe, to the rocks of the Americas took considerable work - it was not a simple matter of matching strata found each side of the Atlantic.
