That works properly only if the magnet keeps its initial power. Howewer, Al-Ni-Co magnets are often degaussed from aging. A degaussed magnet seems to behave properly while aligning, i.e. it still provides some "max brightness" position, but this does not mean that the whole electron beam reaches the screen.

I have at least one reverse example with a bent-gun picture tube, but it could happen from a degaussed magnet as well.

They just have to be well-chosen. There are some top-grade ones (Svetlana, MELZ - just look at the pictures I attached to the previous post), some normal "workhorses", and, as always, some crappy crap hurting the whole reputation. I'm guessing that I should write some sort of choose guide here.
