It has todo with the pattern matching being greedy, not the /x flag.
your pattern will match a '[' then as many characters as possible -
including ']' - until a final closing ']'.
There are two solutions:
1. As shown, match any non ']'.
2. Make the match non greedy: %r{ \[(.+?)\] }x

ps. If you want all occurences in the string, use string#scan instead
of String#match.
