Erm, I dunno. I skipped about a bit but I didn't think it was an amazing comparison;
I've found at volume, it's a lot easier to feel the differences between pickups. There are things you can play that make them sound the same, and things you can play that reveal their differences - the overall output, frequency response, how a hard pick attack chirps or thumps, how clear the low strings are, how and when feedback happens.
Examples of where pickups can matter from parts I play in my band.
1; A song where the distortion comes on and I do a slide from 17th fret on the low E down to 5th with really spanky pick attack. Through the same rig, some pickups make that slide sound really muddy and when I get to the 5th fret it's just fundamental with no definition. Other pickups sound spanky like I want them to.
2; Lightly raking the strings with the back of my nails, with enough distortion on that the notes are *almost* feeding back. Some pickups give a glassy treble as my nails leave each string, some sound bassy without much note attack, others give a more chimey upper mid plucky sound.
If I was just doing hearty mid gain full chord strumming and some blues licks like that vid, pickups would all sound the same to me.
