Interesting. I would say it's *exactly* the same, and I can't imagine
that anyone considers

as two different things: In both cases there are five beats per
(LilyPond) measure, and the beam pattern is 2 + 3. Any additional bar
lines must be inserted manually.
Can you give a counterexample?

Gould allows the above time signature to describe one measure or two.
In the case of one measure, she recommends beaming the 4/8 and 6/8
sections of that measure as 4/8 and 6/8 would be beamed individually.
For 6/8, that would usually be 3+3, not a single group of 6.
4 + 6

I didn't see Gould saying much about the above other than to discourage
it. From the context, my impression was that treating it as two
measures was not in the picture. If that impression is correct, I would
count that as a difference.
Everything else I know about this I learned from LilyPond, which beams
it as a single group of 6. That is another difference.
