The definition of Equity is correct but the example was badly 
worded ... 

What I should have said was ... There is no additional EQUITY by 
utilizing additional buying power but investing the same dollar 
amount because although assets increase, liabilities do as well i.e. 
whether leverage is 1x or 100x, EQUITY is the same until market 
value changes.  When market value changes EQUITY will be impacted 
100x as much with leverage of 100x whether that be up or down.
