if you want to put more than one command in such a command style,you should use brace curly---{},NOT ().The latter means execute these commands in a subshell.Look:
Code:
[ true ] && ( echo "yes,you can use it";echo $BASH_SUBSHELL;)

and this one
Code:
[ true ] && { echo "yes,you can use it";echo $BASH_SUBSHELL;}
