i read an article http://www.sqlskills.com/BLOGS/PAUL/post/A-SQL-Server-DBA-myth-a-day-(1230)-tempdb-should-always-have-one-data-file-per-processor-core.aspx where this was quoted
Depends why you're adding files. If you're adding files just to alleviate contention on the allocation pages, they can be on the same drive. If you're adding files because you're bottlenecked on IO, then yes, they need to be separate.
Can anybody put some explanation here, primarily for this
adding files just to alleviate contention on the allocation pages

If you're adding files just to relieve allocation contention, they can be on the same drive. If you're adding files because you have IO contention on TempDB, then adding more files on the same drive will be a waste of time (more files on same drive does not improve IO throughput), hence they need to be on separate drives.
