The number of concurrent MySQL connections are only applicable if you are using MyISAM tables. Connections are higher due to the number of threads waiting for table locks to be released. If you're using InnoDB, then the number of connections drops dramatically.

For example, with MyISAM and around 600 people online, I often had over 400 concurrent connections. Since switching to InnoDB, I rarely reach 100 connections.
