I'd like to see something there about the function being terminated.
Perhaps, embellishing your suggested text:

"Terminates the last protected function called and calls the function
'error' when the value of its argument v is false (i.e., nil or
false);..."

And perhaps add something like: "The most recent protected call will
contain the error and prevent it from propagating further."[1]

But please take into account that I don't know what I'm writing about. :-)

Best regards,
