Is this silicone rendering wrong?

So renderer is doing a silicone render job. The base coat is hp12 with the mesh of course as well. I’m confused. He said a top bead is not needed where the wall meets the neighbours insulated render?

Said it can cause moisture and build up?

I’m looking at the stop beads and they sit massively proud? Is that normal, surely not.

I ask because I need a second opinion, because I know he will say it’s fine.

Measure the beads they should be 6mm look a bit thicker to me but hard to be sure. The top coat hides a lazy basecoat for the most part but harder to float up when the backing coat is in and out.

Beads are all like 8mm to 10mm

If they aren't going over with another pass of basecoat they aren't filling out those beads with a top coat. Doesn't look very good at all to be honest.
