This is exactly right.

Strictly speaking, cross wound thread isn't supposed to only be horizontal. This is a slight misinformation.

From a blog post I made a few months ago - http://www.archaicarcane.com/standin...s-stack-wound/ -
(To the mods - I am NOT selling anything on my blog, I AM properly quoting the source, AND there's a link back to the QB on that page):

Sometimes you will hear people say that cross wound thread belongs on a horizontal spool or “obviously” cross wound thread should be used vertically only if it’s a cone.

Neither of these statements is strictly wrong, but both are perhaps unclear or incomplete statements.

Because thread has largely been available as cross wound only – with the exception of specialty threads like metallics, silks and heavier quilting threads – and horizontal pins have been the norm on most machines made in the last few decades, it’s possibly correct in most cases but certainly not all – at least not the way it’s stated above.
and

Cross wound thread is meant to come off the top (or the side if the pin is horizontal), and if the spool turns with it, it causes tension issues, because the thread wasn’t expected to have the extra resistance. Look at the image of the sergers below. You will notice that a great deal of design decision has gone into thread delivery. Do you think they’d have that ugly telescoping piece and the huge thread apparatus if they didn’t have to? They do this because sergers are very tension sensitive and thread delivery is very important. Notice how the thread has to come off the top of the cones the way the serger is designed? So too your sewing machine

I think it is because there is too much tension on the thread due to the cone being on verticle pin instead of on a horizontal pin.

I think I wiill buy one of the Superior thread holders. This having to always rethread the needle is driving me crazy!!!!!
I would think that your problem would be more likely due to extra twist on thread and it springing back, rather than too much tension. Technically, it would likely come from the same source, but SOQ's suggestion of raising the foot makes sense, because it will release the tension (and therefore the tendency to spring back) on the thread at the same time, hopefully leaving the thread in place. My biggest reason for having to rethread is that I stop with the needle down, then when I raise it, and the take-up lever goes up, it yanks the thread out of the needle.

I've only serviced one PQ1500, but I used to use a Juki TL-98Q - which is a very similar machine, and a similar thread cutter, and neither had complaints of unthreading, so I think it's likely something that you can address with a slightly different workflow.
