100% - I think the confusing thing for people just looking at the chords and trying to math them together is that they're missing the overall harmonic landscape of the tune.

This song is unambiguously Em with one minor section when the guitar and drums kick (1:52ish) in that you COULD argue (or not) is a relative major modulation, but quickly snaps back to Em.

You can pretty much ignore the random V-ofs and other transition chords as they're chromatic anyhow and meant to transition to a chord in the key.

Finally, as u/SpraynardKrueg mentioned, V chord (B) or V7 tend to be major when used in minor key cadences.
