It's odd for this single-line then statement to cause the subsequent comment to be indented as if within the block. For consistency with the other single-line statements (for, else, while, etc.) it should be indented to the outer scope, e.g.:

Suggested change

	_ |begin
	_1 | if A then{1}
	_^1 | A := B + C
	_^1 | //
	_1 | else{2}
	_^2 | B := C + D
	_ | //
	_ |end
	_ |begin
	_1 | if A then{1}
	_^1 | A := B + C
	_^1 | //
	_1 | else{2}
	_^2 | B := C + D
	_ | //
	_ |end
