Tiger's takeaway was a lot different under Butch and the shaft on the downswing came down a lot steeper. The junk in Haney's swing is with the longer clubs, even as strong as Tiger was and dipping as much as he was couldn't get the driver back on the shaft plane at impact. What's the point in trying to swing it on the shaft plane or parallel to the shaft plane if you're never going to be on it at impact? Impact is all that matters.
The camera is higher in the Butch swing, making the shaft look higher above the blue line than the Haney swing. The takeaways look the same to me. The dip is in all Tiger patterns and is a good thing IMO. So what if he doesn't quite get back to the address plane at impact. The impact in the Haney swing was all that mattered while he dominated the tour all those yrs using it. As the country song goes, "If that's wrong, I don't wanna be right."
