Proves to be the correct decision, when stronger overhead stirring is applied in the beginning, so much hydrogen gas is evolved that it pushes the reaction mixture all the way up the first condenser and sometimes a little bit into the second one. One truly giant metre long condenser would also work, but when carrying out a 500 g+ reaction ina 20L flask, I would use 2 600 mm or 2 1000 mm condensers connected to separate necks.
