If you contact the guy in charge of Totem Tech support you will get a different answer than the one your received from the sales guy. The dots do denote quality control from a tweeter matching perspective and they also denote different tweeter versions and productions runs. In a sense it is about quality control in the context of speaker matching components.
It is okay to move the dots since the speaker's makeup/version is recorded by the serial number.
