[gentoo-user] OT expect script question

In my response matching I would like to have a catch all so if nothing
specific is matched I can take an action, but when I include the "*"
option, it is selected even if string1 matches. From the expect man page
"In the event that multiple patterns match, the one appearing first is used
to select a body." So why are actions3 getting executed when string1 is
matched? If i remove the "*" section, string1 is matched.

expect {
    "string1" { <actions1>  }
    "string2" { <actions2>  }
    "*" { <actions3> }
}

expect *
Here the * matches anything. This is like saying, ?I don?t care what?s in
the input. Throw it away.? This pattern always matches, even if nothing is
there. Remember that * matches anything, and the empty string is anything!
As a corollary of this behavior, this command always returns immediately.
It never waits for new data to arrive. It does not have to since it
matches everything.

Could it be that it just matches empty without waiting for anything?

Perhaps, but  that would only matter if it is processing per character, not
per line. I had assumed that it would not evaluate the blocks until it
received an End of Line character, but I will test that assumption. Thanks
