The 5-30 minutes time. Gives the oil enough time to settle to the correct level after shutdown, but not too long as for the oil to settle too much.
When you get a chance check an engine within this time. Then check several hours later. It can show several cans lower.

As basically mentioned, its to ensure servicing to the correct level. You will over-fill the engine if you fill to the top of the sight-glass after the engine has been shut-down for several hours (not usually a problem on the CFM56 as they use plenty of oil anyway!)
