I assume you're talking about the Sion strat where you die a lot but take towers quickly with passive. I'm pretty sure people built a Tiamat and the lethality items (. I think it's with Glacial Augment so you can stick to people in your passive.
As long as you have a lot of AD (and armor pen) you'll have good burst damage and passive DPS. It's a lot more efficient to die to tower and get executed, then use your passive to deal a bunch of damage to the tower. If you just run up and die to your lane opponent for a little bit of tower damage, it doesn't benefit your team.
I haven't seen an "inting" Sion in a while so I'm not sure how viable it is at the moment. At least you have a decent amount of impact by getting towers even if you're feeding, but ideally you only die when your team will benefit from your death.
Edit: I've been told the tower-pushing build is . The lethality build uses the passive more for killing champions.
