The help documentation says that the pause icon is supposed to make a player pause for a second. It appears to me that players are pausing about 1/2 second (maybe a little less) for each pause count.
The pause button works the same on all platforms. Over time, the simulation has changed a little. You are correct: Pause will delay for 1/2 second, and the doc should be updated.
If the pause command has the same short length on all platforms, then it's just the documentation that needs to be changed. If Pause has a different timing on the iPad 2, then plays that work on other platforms could break on the ipad 2.
