Apple Testing Multitouch Gestures for iPhone 4?

According to BGR source inside Apple, apparently Apple is internally testing iOS 4.3 multitouch gestures on iPhone 4 as well as iPad. The below screenshots, it looks like 4 or 5 fingers gestures are the same as the iPad in the first beta of iOS 4.3.

This is not shocking as Apple's will remove home button from next generation devices (iPhone 5 and iPad 2). Engadget thinks that the iPhone 4 could have a bigger screen or it could just be placeholder text from iPad and less fingers will be required if it goes primetime.

As most of you know, Apple won't make this multitouch gestures available in the public release of iOS 4.3. So, why are those gestures? Well well well, may be iOS 5?
