I think he means how much fireworks do they have.
A few years ago, it seemed like most shows (in general) had a few elements in the sky at the same time. But lately, it's one at a time while the music plays. This happens at a local park down the street from me, and also seemed to be the case at SWF for their show.
In my case, I went on July 4th, and they had two shows with the Orlando Philharmonic playing live. There we're some songs where fireworks didn't even go off. Most of the time, it was one element, after another. The finale was about 30 seconds with a nice display, but it was quick.
I'd have to say they're not going all out on the fireworks since they have so many shows to do. It's all computer controlled, and they have a laser show going at the same time.
It's worth seeing, you'll walk away saying it was good, but you won't go away saying "wow" if you're a fireworks fan.
The other alternative is to go see a big display by a major company. Only problem here is fighting the crowd to get there.
