When a recipe calls for 1 - 2 bunches of scallions do they mean 1 bunch equals the whole bundle you buy as 1 bunch?

A mature scallion plant has multiple green "stalks" sprouting from it's white base, and because there are more than one "stalks", one whole plant is consider a bunch. In recipes which call for using the green part of the plant as a garnish, one would only chop a tablespoon or so of one of the "stalk". Whereas, in a recipe calling for one or more bunches of scallion you would use one or more whole scallion plant.
