You are correct.
The cult members opportunistically and inappropriately misapplied or misinterpreted, or both, a section of the document.
What Section 6(b) details is e.Digital's right to withdraw a registration statement, however this clause is irrelevant to the registration of the Series D stock.
Specifically, if e.Digital were to file a registration statement unrelated to the Series D stock, the Series D holders may elect to convert their shares and participate in the filing.
However Section 6(b) permits e.Digital to withdraw the unrelated registration statement at the company's election without recourse from the holders of the Series D stock.
