VXX, VIX and volatility questions

Let’s see if I understand this:

VXX is the short term VIX futures and should go down if S&P volatility remains low. If the S&P drops a few points then short term VIX futures rise and as a result VXX rises. However, if the S&P rises a few points then short term VIX futures hardly moves or drops and as a result VXX stays the same or drops.

If S&P goes from low to high to low VXX rises. If S&P goes from high to low to high VXX stays the same or drops. But cases are volatility. Shouldn’t VXX rise no matter the direction of volatility?
