“In a pyramid structure, meetings are needed at every level to gather, package, filter, and transmit information as it flows up and down the chain of command.
The higher you go, the more lines converge.
Decisions are naturally pushed to the top, as it’s the only place where decisions and trade-offs can be informed from the various angles involved.”

This clearly and accurately describes pyramid structural organisations: many meetings are required – for people at different levels to catch up and make decisions.
