trainers edge vs. donna/gary/jerry

[shanahan]

OK, help me out here...what is the differnece between a \"bunny hop\" and the term
\"false start\"...the legs?  There is an educational video out that say a horse who is false starting (in the post parade) is ready to run a top race...but Larry Zap on the radio says Barbaro was \"bunny hopping\" meaning jumping up on both back legs...I  am confused s to the differnece and would appreciate some insight.
