Potential Typo in Request Handling - "r.Close" misset to False?

Lines 99 to 108 in 3ec0782

	// When server reads http request it sets req.Close to true if
	// "Connection" header contains "close".
	// https://github.com/golang/go/blob/master/src/net/http/request.go#L1080
	// Later, transfer.go adds "Connection: close" back when req.Close is true
	// https://github.com/golang/go/blob/master/src/net/http/transfer.go#L275
	// That's why tests that checks "Connection: close" removal fail
	if r.Header.Get("Connection") == "close" {
	r.Close = false
	}
	r.Header.Del("Connection")

It seems that req.Close should set to true when the "Connection" header contains "close" according the comment above.
However, in the above snippet, r.Close is being set to false. Is this a typo or I misunderstanding it
