You get a different generation curve (more energy in mornings and evenings) with vertical bi-facial panels. Though this person is in a woody area which might not see that benefit.

That’s specifically for e/w bifacials, you don’t get that with N/S panels.

North/south bifacial shifts the generation seasonally, trading much less in summer for a bit more in winter when the sun is low.

[masklinn]

Indeed.
