[Haskell-cafe] Language semantics

I have a tricky little question...
Suppose I write a function like this:
| gard1 = ...
| gard2 = ...
| gard3 = ...
| gard4 = ...
According to one tutorial I read, if pattern1 matches, pattern2 will
never be tried, even if both guard1 and guard2 fail.
And according to another tutorial I read, if pattern1 matches but all
guards fail, pattern2 *will* be tried.
Can somebody comfirm which one is actually correct?
