Let's see if others agree with my definitions - Flooding means too much liquid fuel somewhere - in your case chances are while the bike was other than upright too much gas got into the carb which will make the fuel mixture too rich until you've used up the excess gas -probably more than a few feet of travel. You probably should have rev'd the engine a few times until you heard it running nice and clean.
Flooding can also mean having liquid gas in the combustion chamber which is not good. Often happens on a choked, cold engine that doesn't start right away. Gets the plug wet and keep it from firing properly.
"Loading up" is usually refering to a way too rich fuel mixture affecting the performance of the engine often leading up the plug "fouling" from the excessive carbon generated from the unburned fuel. The carbon deposited on the plug actually shorts out the electrical impulse so no spark.
Usually, if you can get the bike started, and it was set up right before the dump, a loaded condition will clear out if you rev it a little or ride at a quick pace.
