In the proper context it is not bad advice! It is actually quite necessary when applicable, obviously as in the case of a corrupted/truncated .vmsd file or a .vmsd file that does not contain all relevant information to the actual state of all Snapshots. This unfortunately occurs for a number of reasons and has to be dealt with when necessary and when applicable the most expeditious method is to delete the .vmsd file, take a Cold Snapshot and immediately delete it to consolidate the orphaned snapshot(s). If consolidation is not acceptable at that time then if necessary the .vmsd file can be manually edited/repaired/recreated to a functional degree from information in the vmware.log files although it may not be identical to the original before the issue occurred. The bottom line is, there is never any good excuse not to have and maintain proper regular and ongoing backups of at the very least User Data, of which I consider a Virtual Machine to be, as well as the Host system itself! 
Additionally deleting the .vmsd file does not delete the Snapshots, the Snapshots are still there, they just don't show in the Snapshot Manager!
If the future don't make statements when you really don't know what your talking about!
