Looks like yellow base, green around the eye/gill plate then masked the white then the bars. He looks like he repositioned the netting though not sure at what layer but if you have 2 brushes you don't need to remove the netting, That's how I see it.
Check out lee butz video's on youtube he made these netting holders that the larger production companies even use it looks like a tuning fork and really helps when your doing mask work, also if you don't have them yet get yourself some helping hands from harbor freight they are cheap ($2-$3) and are a very versatile tool to hold you work freeing your hands up.
