In other words, the whole GeoServer architecture is streaming, meaning, the result you see in WFS is not the actual result (loading it in memory would take just too much RAM), but a tool to access the data. When the output format does its work, it will actually start pulling features out of it, and that's when the query is run, loading a page of features, encoding them in output, throwing them away, moving to the next, and so on
