I find it fascinating that this was the response you got. In post #27 above, the link I provided (in case nobody bothered to click on it) goes to a blog whose author, Jenny Lyon, also contacted Pilot and got completely different answers.

I called the Pilot pen company and asked for a representative knowledgeable about Frixion pens and their use on fabric. She was quick to note that Frixion pens were not designed to be used on fabric!

The Frixion ink is actually a combination of two things: gel ink, and a thermo ink. The addition of the thermo ink is what makes the gel ink disappear with heat. But note, Frixion pens are basically gel pens with some added thermo ink. That means that you are putting gel ink on your quilt when using Frixion pens.

Because so many customers were using Frixion pens on fabric, Pilot did some testing to try to remove the stains. She noted that just like removing any other ink stain, sometimes you would need to spot scrub to remove the mark.

(see above quote re: washing ink out)
That ink will disappear only because of the thermo ink - the gel ink is still there on your quilt unless you take additional steps to remove it.
Jenny Lyon's post has information about what products to use and how to use them to remove the ink.
Here's what I take from Jenny Lyon's conversation with the Pilot rep she talked to:
1. Frixion pens combine gel ink and thermo ink. You are marking your quilt with a gel pen that disappears.
2. The marks
will reappear if the quilt gets cold unless the mark is completely removed with an ink remover. Even after a thorough steam of the marks, they will reappear in the cold. This is part of the inherent chemistry of the ink combination.
3. To completely remove the ink so that it will not ghost or reappear in the cold, you will need an ink remover and also may possibly need to scrub the area. The manufacturer has tested 2 products (see Jenny's post) and found them to be fairly effective in removing the ink.
4. Frixion pens sometimes leave a ghost mark after steaming. This is the thermo ink showing on the quilt, not the gel. The Pilot rep said to rid the piece of ghost marks you would need to treat it with the ink removers listed above.
P.S. A personal word about gel ink:
I had a bad experience a few years ago with gel ink. My husband dropped a gel pen on a very expensive business dress shirt and didn't realize it for several minutes. The ink wicked into the cotton and made a huge blot about 3" in diameter. I didn't want to experiment with stain removers on his dress shirt, so I replicated several stains on some scrap cotton and tested various removal methods to find the best one. I tried EVERYTHING. Bleach, hair spray, 4 different commercial stain removers, carburetor cleaner, you name it, I tried it. I sent one of my stained scraps to the dry cleaners and had them work on t. I did a ton of research on the internet and tried everything everyone else recommended. Nothing worked. I finally stumbled across a law enforcement website that recommends you sign things like checks and legal documents in gel ink, because bad guys can't bleach your signature out, no matter how hard they try. That was it for me - if the professional crooks can't get gel ink out, then nobody can!
