He starts with a code example that would work with a previous version of PHP/PDO that would allow for the binding of a single value to multiple places in the SQL statement. But:

Sadly, this is no longer the case in PHP 5.2.1. For valid reasons of security and stability in memory handling, as noted to me by Wez Furlong, the above behavior is no longer supported. That is, you cannot bind a single parameter or value to multiple identical placeholders in a statement. If you try it, PDO will throw an exception or raise an error, and will not execute the query. In short, you now need to match exactly the number of bound parameters or values with the number of placeholders.

Unfortunately, this is used quite often in Paul's Solar framework, so an update to the Solar_Sql_Adapter::query() method has had to been made to allow for the binding of multiple items automatically. It works by incrementing the bind location (like ":foo") with numbers at the end - simple and effective - and you can still pass an array to it and have it automagically work.
