SyntaxInformation and OptionsPattern

Here is a slightly modified example from the SyntaxInformation Function
page:

 

Options[f] = {aaa -> 1, bbb -> 2}; 

 

SyntaxInformation[

   f] = {"ArgumentsPattern" -> {_, _, OptionsPattern[]}};

 

f[x, y, 3, aab -> 2] 

 

The "3" is clearly not an Option, and it exceeds the allowed number of
arguments - so why isn't it flagged in Red?
