As far as I can discern, if indeed it's got a Foxconn tag on it, they probably purchase the cell itself from Chimei Innolux (with whom they have a partnership) and put the finishing metalwork and connector around it. Chimei was slated to make the iPad 3 Retina display originally but apparently had yield issues so the contracts went to LG. Now that they have had some time to work on it, maybe they're able to churn out these replacements.
There are very few companies who manufacture LCD cells (the bare glass, sans metal or backlight films), it's very expensive to run a fab. Mostly a few titans run the fabs and everyone else buys raw cells from them and puts their own backlight and controller and whatnot around it. Even though Foxconn is by all means a titan manufacturer, I don't remember seeing that they owned a fab. Certainly if they did you'd see more Foxconn branded panels around - you don't maintain a fab just to make one or two products, it's not economically viable.
Did you see that in the seller's own photo there are two stickers? Interesting. I think the one sticker you have must be an Apple part number and serial, and the second is about the panel itself. The seller's photo appears to be of a LP097QX1, if I can make out the characters properly in the low-res photo. Classic bait-and-switch
It would be unlikely that the ribbon cable is a different size... they are very precisely sized for the amount of space in the chassis, and trimming the quarter inch necessary to make it fit the board would probably make it not reach in a real iPad assembly. I thought maybe the 3 and 4 had different sized tails, but according the the iFixit iPad 4 teardown, they're practically the same: http://d3nevzfk7ii3be.cloudfront.net/igi/xviDmCRhiMdKiVpG.medium
. Presumably the board designer wanted to have the buttons exposed on the top of the panel and the connector was placed where it needed to be to sit straight, and there just wasn't enough room for both. On my controller I alleviate this issue by extending the buttons to the lower-right corner via a wire harness and a small second board.
