unclear code in MyTextSanitizerExtension class

In the method codePreConv()
$patterns = "/[code([^]]*?)](.*)[/code]/esU";
            $replacements = "'[code\1]'.base64_encode('\2').'
'";
$text = preg_replace($patterns, $replacements, $text);[/code]

the regular expression [code([^\]]*?)\], why do we need the "?" after "*"?

As I know, the [code([^\]]*)\] still works.
E.g. The original string is "[codeabcd]", the expression [code([^\]]*)\] still can get it. So can I delete the "?" from the expression?

The question mark in the regex makes the asterisk lazy, to make sure it stops before the first closing tag rather than before the last one, like a greedy asterisk would do.
