Since what matches to the right of the `\/' match token is

Although the match token is, indeed, rightward-greedy, the
expression is not so descriptively helpful here. Let's put it
another way: without the match token, procmail will only go as
far to the right as it absolutely needs to, to save effort.
So, given a choice of matching one whitespace char or many,
procmail will stop at one and say, "I've satisfied the
criterion!"
The match token in the OP's example (cut here) simply
started matching at the next char (denoted by a regex dot)
after the criterion cited. That character can easily be
more whitespace.
