I don't see how the functional moves in Capoerra came from BJJ. There are two styles of Cap. one (Angloa) deals a lot with low strikes and ground work (not so much as the grappling styles of BJJ)and is performed (in practice) quite slowly (in comparison). 'Regional' was developed by Mestre Bimba from old cap styles and added aspects of other styles, like karate. Bimba also introduced set forms of moves, similar to kata. Prior to this it was banned in Brazil as it was something streetfighters, thugs and bandits endulged in.
Basically, Cap involves a lot of kicks and continuous stand-up movement in a dance style as opposed to the ground based grappling of BJJ. I can't see how they can be confused (or compared). (history taken from The Little Book of Capoerra; by Nestor Capoerra)
