[antlr-interest] small question

[DVLeonid]

Dear antlr-interest,

  I'm confused while reading ANTLR meta-lang spec.

At "Fixed depth lookahead and syntactic predicates" part there is
sample:
  
class parse extends Parser;
a       :       (A (P)*) => A (P)*
        |       A
        ;

I cannot understand how ANTLR recognize

AB

as:      A(P)*, where amount of Ps is zero, is followed by B
or as:   A is followed by B

In common sense it should be recognized as ... I can't understand : (
ambiguity penerated in my mind...
