Quoting from the first paragraph of Section 4.1: "Therefore, the first 
few samples produced by the decoder do not correspond to real input 
audio, but are instead composed of padding inserted by the encoder to 
compensate for this latency."

of samples have to be dropped because they're simply invalid"?
