They are the same symptoms. Here are photos of mine, a semi damaged spot and a very bad one.
The symptoms don't look the same to me. Gotsqueeze's patches are circular, which makes them less likely to be caused by an insect pest whereas your patches are irregular which could be a number of things. We need to see more of the larger environment but if you'd rather not post a picture that may be identifying of your location then can you tell us if this grass is walked on (the second picture patch is somewhat elongated and looks compacted but can't see how long the elongation is - rather looks like foot traffic), if it is near a road (salt injury), whether irrigated, fertilized, any tree roots etc. etc.
One thing you could do if you don't think the problem is somehow environmental is take a watering can with two or three tablespoons of dishwashing liquid in a couple of gallons of water and pour some of it on the turf around the bare spots. You don't need to pour all of it on but just enough to soak in to a couple of square feet or so. Wait about five minutes and then see if any insects come out. This is a hands and knees job! If you don't know what the insects are (they aren't necessarily all bad) then try and get a picture of them so we can check them out. You'll need to flush the area you tested with plain water afterwards to dilute the soap so that it doesn't add to the damage.
