The suggested approach is merely a heuristic that reduces the impact of a zipbomb. An attacker can circumvent the heuristic. In best case scenario, the approach just increases the cost factor for a successful DoS. For example an attacker may have to upload 10 larger zip files instead of one smaller zip file to fill up the disk space of a server.

The correct approach is to always verify all data from untrusted sources. It's the 101 of application security.
