I could not reproduce this - are you sure you reported it correctly?

$ foo=`echo 'beriberi'| { grep -E -e '(....).*\1' >/dev/null 2>&1 ;
> echo $?; }`
$ echo $foo
0
$ echo `echo 'beriberi'| { grep -E -e '(....).*\1' >/dev/null 2>&1 ;
> echo $?; }`
0
$ echo $BASH_VERSION
3.1.17(6)-release

parsing in bash-3.1 that have been previously reported, such as
