I see what he means
I stared and stared----notice the angled lines in the lid reflection, you can follow the lid opening reflectiion at about 30 degrees off, then about 2 inches away you get the flat rear lip opening, and then about 2 more inches down the reflection seems to show another parallel line refection like a genuine WhilpoolKenmore flat rear-edged tub cover would reflect, as opposed to this hybrid circular tub. Cameras and eyes and posted pics and relections in a flashbulb are all less than excellent, but I stared quite a bit and can somewhat see what he's talking about in the reflection.
OR, purely by luck, are the spaces between typed words on a few lower lines in the lid leading to what looks like a 3rd line of reflection?
Let's all get our copies of Sherlock Holmes books and have fun!
Any way you look at it, it's a beautiful and rare machine.
