A "!" instructs Asterisk to match *0 or more* characters [1]. Since
you have already provided all the digits to match that pattern,
Asterisk correctly detects that it has matched the extension and
begins execution.

If you want to tell dialplan execution to wait for more digits, you
can use the Incomplete dialplan application [2]. It exists
specifically for this purpose.
