Here is my take on it.
A move above the left trendline is a volatility expansion in an uptrend channel and a move below the right trendline in a downtrend channel is a volatility expansion.
A move below the right trendline in an upward channel is breakout and a move above the left trendline in a downward channel is a breakout.
A move above the left trendline is a volatility expansion in an uptrend channel and a move below the right trendline in a downtrend channel is a volatility expansion.
