He didn't say 'just'.

Entropy encoding (cabac/calvc) is one of the major knobs to turn if
processing load on the target should be minimized. And the price to
pay for (en/decoding) speed is almost always the same, i.e. higher
bitrate per quality. I wouldn't be surprised if he already guessed
that much.
