Dots will line up 2 times - once will be right, the other time will be 180 out. So just making sure the dots are lined up is not enough, must be lined up on the #1 compression stroke.
Compression or exhaust stroke is determined by valve timing. Valve timing is determined by cam position.
Lining the dots up ensures that #1 is TDC on the compression stroke.
