Not quite. that would look like
	if x>y -> [e1, e2]; true -> [e3,e4] end.

Basically,

A=if x>y ->
     e1,
     e2;
   true ->
     e3,
     e4
   end.

Is just to show that 'if' returns a value, and it returns the return- 
value of the last statement in the clause (a section of the 'if' that  
begins with "EXPRESSION ->") of the 'if' expression that is  
evaluated. The semicolons separate those clauses. That particular  
expression binds A=e4.
