Designer Help: @V2IF Typo or a sack of rice fell over ?

I did some investigation on how often an @function is used in the mail template. It is absolutely useless information, but I wanted to test the usage of  Teamstudio Configurator from Lotus Script.

Here is a snapshot of the resulting view

Reading through the results I stumbled upon the @V2If formula. This formula is used 21 times in the mail85.ntf template.

But why should one use this @V2If in a template that would never be opened on a Notes 2 client. I looked in the Designer Help to find out if there is some difference betweeen the @If and @V2If .

To my surprise I found the following sentence in the help description for @V2If

Note  In applications created with Lotus Notes prior to Release 4, the @If function is automatically renamed to @V2If during the upgrade to Release 4.

If I understand this sentence correct, all @if entries in the code of an application created in Notes 3 are replaced automatically by @V2If when you convert the application from Notes 3 to Notes 4.

IMHO this must be a typo, because this would not make any sense. @IF was introduced in Notes 3. Why should one convert this to the old @V2IF when you are obviously using Notes 4?

Oh listen, a sack of rice fell over in the Yunnan district …
