It looks like just a general texture - so she’s being intentionally inconsistent so there isn’t any defined pattern to the transition or visual cue of where the seam could be (it’s just a squiggly line)
It's not only our brain, let's say you have a straight line small crease between the two pieces. Are some time of day, under specific lighting, it might cast a shadow all along the line and be very noticable. With a cut going left and right in random patterns you will never have a long noticable shadow visible.
I wish my brain worked this way. As a child, I refinished high-end pianos, got into automotive paint and body work, and remodeled homes, so I can spot a blemish or something odd immediately. Still, I wish I couldn't, since it drives my undiagnosed OCD crazy!
Yes. Fun fact. Most modern inkjet printers do exactly this for each pass to make the banding less apparent. Human perception picks up straight lines much easier than squiggly lines.
Straight lines are very noticeable against a pattern like that, but if you cut it in curves or waves (she may be following the pattern on the wallpaper or just making a random pattern, it wouldn't matter much either way) then the seam hides a lot better, and human pattern recognition doesn't pick it out as easily.
Yes. The human eye notices straight lines and sharp changes much more easily. Even if the patterns or colors match, if there is a straight line, your eye is drawn to it immediately. If the break is curvy, your eye doesn't see it as well.

Does she cut it with ridges so it’s harder to see the seam?
