What does the 10b5-1 badge mean on these transactions?

Of Brosius Mark's 53 reported transactions in the last 12 months, 24 (45%) reference a 10b5-1 trading plan in the Form 4 footnotes.

Are these all the transactions Brosius Mark has executed?

This page shows SEC Form 4 transactions on record in Pactolio's tracked universe for the last 12 months.
