In order to have an accrued expense you have to have a number to determine that amount.
So the salaries of all the directors are published so that they can determine the value of the accrued expense (in this case - salaries) and then the Directors choose to be paid that amount in securities.
If you were in their shoes why would you do that?? I don't think it is unreasonable to believe that they are convinced of the path they are on. But that's an opinion (mine) so you'll have to form your own - but the filings are clear that taking stock for pay is what they are doing.
