http://dlang.org/statement.html

Statement:
  NonEmptyStatement

NonEmptyStatement:
  NonEmptyStatementNoCaseNoDefault

NonEmptyStatementNoCaseNoDefault:
  AsmStatement

AsmStatement:
  asm { }
  asm { AsmInstructionList }

AsmStatement does not take semicolon at the end, then

if(1)
        asm {};
    else
        asm {};

is mostly same as:

if (1) { asm {} }
;
else { asm {} }
;

and the 'else' part is stray.

 Why asm statement doesn't follow common rules?

One reason is because although AsmStatement is formally a statement, it is
actually close to a BlockStatement (AsmInstruction is close to regular
statement) and BlockStatements don't have ";" after them (like aggregate type
declarations and enum declarations).
