I am doing exactly that and it works great. The only challenge is that
some cuts with the guide end up being a bit of a reach (cutting a 4x8
sheet into two 4x4 sheets, for example) and the weight and balance of
my Skil Mag 77 make it a little harder to operate with one hand.

The reason I ask is that I already own a wormdrive. I don't own a
circular saw.

Yes, but normally referenced by type (table, wormdrive, etc.). When I
say circular, I mean the short stubby electric hand saw such as:

It really doesn't matter. I'll want a straight cut in any plywood I cut.

I have a table saw but it's not setup to cut 4X8 sheets of plywood. Not
enough table space/support to feed a single sheet by myself. I have
done this and found it to be inaccurate - I do not get a straight cut.
That's why I was looking at the guide.

what do you mean by circular saw? table saw? as far as I recall the
blade on every worm drive saw I've ever seen has been circular.
you also didn't give enough information about your plywood.
so table saws are great for precision cuts in high quality plywood,
providing the saw is massive enough, has adequate infeed, outfeed and
wing support and that the blade is appropriate for the material being
cut. of course, such a setup represents a significant investment in
cost, setup and maintenance time and dedicated space.
with some care, cutting results that come close to the quality of the
above setup can be had from a handheld circular saw, be it worm drive
or not. the things that make a difference are:
*work surface- the plywood needs to be evenly supported. some folks
like a sheet of styrofoam laid down over the floor. others build
specialized cutting tables.
*cutting guide- the one you linked to will work just fine, assuming
you take pains to get it straight when you build it.
*the shoe of your saw- the reference edge (the side of the shoe
that runs against the guide) has to be parallel to the blade, or the
saw will drift from the cut line and/or blow a lot of splinters out of
the edge of the plywood.
*the blade- it has to be sharp, run true and have the right tooth
geometry for the cut you're making.
That jig will work on "any" type of circular saw. It will also
work with routers.

I use a guide similar to that one, except I used a strip of aluminum
channel for the guide. Leaving the 1 or 1 1/2 inch on the left allows
room to clamp it in place. Works great. But I don't have a worm drive
saw. Can't see where it would matter.

Using a wormdrice saw for standard plywood is a little overkill,
unless it is real thk. A good 2 1/4 to 2 1/2 hp circular saw will work
fine on standard to 3/4 in thk plywood. just be sure to use a good
carbide blade and take your time.

A shop made jig like:
<http://benchmark.20m.com/articles/CuttingSheetGoods/CuttingSheetgoodsWithCircularSaw.pdf>
Will work fine with a worm drive saw, as long as you cut the jig with
the worm drive saw.

It will work fine. Just build it with the fact that your saw blade is on the
left. I have a Milwaukee circular saw with the blade on the left.
I prefer it to the ones with the blade on the right because it seems easier
to eyeball the cutting.
My cutting guide is just like the one shown but designed for a "left blade".
