I've found this seems to happen more with LOF than WOF - but it can happen with both. It's good to really look over your fabric before you start cutting for borders and longer pieces. I have a long background of sewing garments, and lots of plaids - I think that helps to make a person way more aware of pattern placement when working with any type of printed fabric.
One of my pet peeves is buying clothing where they didn't worry about how the fabric pattern lines up. My friend has a nice pair of wide leg pants and the fabric has a very prominent deep diagonal print. One one leg it lines up very nice, on the other the colors make it look like she's got something running from her crotch down the inside of the leg.
