Pretty much the same you do with an axe, and I speak from personal
experience of having done it a couple of times. Does it work as well?
No. Does it work well enough? that depends on the situation, but it
did for me... the sort of places you're using a pole for support in
preference to an ice axe it ought to.
Why wasn't I carrying an axe in my hands? Because I was skiing!I will take your word for it, but I'd still like to know how you use a
pole to self-arrest, and you can't get away with saying "pretty much the
same as you do with an axe" because they are completely different in
shape, size and rigidity. And your practiced ice-axe arrests are going
to be no use at all, you need to practice the ski-pole arrest, with
crampon complications.
If you spend a lot of time skiing you can get to practice using a pole
for arrest. You can also practice with the added complications of two
skis still attached, or one ski still attached, or both skis detached!

The pole is surely attached to your wrist at the top with a strap (or
do ski-pole have sliding straps?), making it impossible to get hold
of the stick near the point, which is the only way I can see you
stopping a slide.
That is an interesting point. Very often when skiing, particularly
ski-touring you don't use the straps. When traversing a slope in
walking mode you frequently have to hold one pole lower down on the
shaft than the other, and when you change direction you need to change
the grip on each pole. It's similar to changing your ice axe between
hands. If you have your wrists through the loops it just slows you down
and makes this adjustment of grip difficult, for both use of pole (and
similarly for an axe). Secondly in a situation where you might fall or
be avalanched it is often a better option to be able to let go of your
pole(s) (and also in some circumstances your axe) rather than have them
flailing around at the ends of your arms, possibly causing more injury,
or assisting in dragging you deeper into the avalanche.
The technique for using a pole for arrest, assuming you haven't got your
wrist loops on, is to discard one of the two poles and then to work your
hands down the shaft of the other until you can apply pressure nearer
the tip, forcing it into the snow.

The poster is proposing to go where crampons are needed with only
poles as backup. I can only assume that he is planning never to fall,
or never to go where a fall will put him in danger of sliding over a
drop. The former case is sheer madness, so he must be talking of
terrain that is benign, gentle slopes or none at all and masses of
room to stop with no danger of a cliff spoiling your day. Not the
sort of terrain I have ever come across on winter walks, hence my
choice of axe always, crampons sometimes.
What about winter walks in terrain such as you might encounter in the
Yorkshire dales, or the Peak District, or the South Downs? There are
also plenty of walks within Wales, the Lake District and Scotland where
you might encounter similar terrain. Certainly I can think of lots of
walking terrain in the Alps and the Jurra that offers similar winter
walking potential. In such circumstances as I've pointed out before,
poles, snow-shoes (and perhaps crampons), together with a snow shovel,
probe and transceiver, are a better first choice than an axe.
