I believe it's been discussed before here, but maybe not…?
There are some issues with the way he "measures" things. First off, any one specific PGA Tour player's pattern isn't 65 yards wide. That's ALL PGA Tour players. A player whose Shot Zone is 30 yards wide 90% of the time can occasionally flare one right. Lefties may have different patterns than righties. We don't know what the wind was doing for everyone, or where everyone was aiming (someone aiming left side and missing a bit left + someone aiming right side and missing a bit right creates a falsely wide Shot Zone). His patterns don't care whether someone is driving it well that day (or "lately") and thus has a smaller Shot Zone to take on more narrow lines, or whether someone is struggling. They're all just lumped together.
When he takes the shot patterns from par threes and tries to apply them, they're even more terrible, as we really have no idea what the intended target of each player is.
Then, whether you happen to hit it down the left side or the right side is down to where in your shot pattern that particular shot happened to land. Not that you intended to play down the left side or the right side (assuming you're optimizing your strategy anyway).
Though that's a bit more how Tour players
should think, and though many are moving in that direction, they still aren't fully there yet. For example on the 5th at Muirfield Village, too many players try to play a line that's got about five yards of "miss" room right - the trees on the corner. Yes, many will bail out a bit left, but their lines should be about 10 yards left of where they often aim. They'd score slightly better from back there if they aimed a bit left. They'd average a slightly longer second shot in, but they'd have more of them, and fewer shots from the treeline/rough.
Generally speaking to what I think the actual topic is, though: width is irrelevant on the PGA Tour. The guys can fly just about anything onto the green and stop it. In our LSW work we've not seen any difference, really, from players hitting from the left side of a fairway to the players hitting from the right side of a fairway (or in the center) to right or left pins. Ditto for the right and left rough to either set of pins. From any distance. The numbers are incredibly narrow.
IMO width can matter for amateurs, who need to run the ball onto the green more often, and so width and angles help them avoid bunkers and/or use ground contours before or on the greens to help feed the ball to locations (or away from locations).
