I don't know what the last album Joe actually helped him compose leads on - it might have been Kill 'em All or Ride the Lightning where he stopped, as the band started to get bigger - but Satriani was clearly a much bigger influence for him back then, whereas these days it seems like he does a lot more pentatonic shred.
To briefly (heh) return to vibrato... A buddy of mine asked me to play music for his wedding a few weeks back, and asked me to do an electric guitar version of Pachelbel's Canon for the recessional (yes, he sent me the video of that asian kid doing that cheesy rock cover, and asked if I knew the guy. And no, I did it in a very different direction than that, because that arrangement sucks). I spent a week or two with a violin score, arranging it for lead guitar and then practicing it to make sure I could nail it even when a bit nervous playing in front of an audience. Given the constraints and the fact it was an outdoor wedding, I was playing with my half stack on the edge of a field and my Flashback X4 providing accompaniament support as a looper.
So, first, that's two weeks of my life I'm not getting back. Second, however, I found myself thinking that the song really started to come together once I started focusing on my vibrato, and being sure to add it on any note I was holding for more than say a 16th note. I just finished recording it for him the other night (the video guy was an uncle of the bridge and ended up getting sick before the wedding and couldn't do it, so they recorded all the spoken bits at the reception the next day and had me record all the music I played) and I wasn't thinking about it too closely then, but...
Really, I think when you start playing classical music on electric guitar, you REALLY start thinking about vibrato. On a rock/shred solo you don't necessarily notice it, but when you're playing classical, suddenly the vibrato is glaringly absent, on violin music. It's no wonder Yngwie has such an awesome vibrato. He HAS to.
