No, they don't. You need to listen much more attentively to what people are actually saying. People are bonded together. They are bound together. bond bonded bonded bind bound bound Now you can check the dictionary to find the small difference.

to me it is pretty simple: bound= is in reference to a direction i.e. we are bound to get there or as already stated, on a northbound aircraft etc. Bond= is related to a connection between two or more items i.e. this team has bonded closely together or they share an emotional bond

bound also has other meanings possible to happen (adj) there is bound to be on course that fits in with your academic, personal or professional commitments. head toward (adj) a northbound aircraft where are u bound?
