What traditional brewing context does the pyramid design effectively mimic regarding space?

Answer

The generous space afforded by a traditional teapot or strainer

The fundamental design goal of the pyramid shape is to counteract the spatial limitations imposed by flat tea bags. By providing significantly more internal volume, the design allows the dried tea leaves to fully unfurl and circulate as they absorb water. This capacity to expand effectively mimics the abundant, generous space that is naturally afforded when brewing loose leaf tea in a traditional, full-sized teapot or a conventional strainer basket.
