In schematics for the 555 Timer Chip in Schmatics they do not show the hookups as

1, 2, 3, 4, and 5, 6, 7, 8 in vertical sequence. Many scchematics illustrate
the sequence of leads on the chip as all mixed up. The draw is clear, but the sequence as to the chip is all mixed up.

How does that help?
 

Always use the pin number, they are moved around on schematics to make the diagram easier to follow and sometimes to group together similar functions. So really, it is just for convenience and clarity. When wiring the devices up, the pin number (or name) is paramount, where it lies in the symbol is unimportant.
