It's good for both !!! Visualy confirm the placement, and then it
makes for a great way to get solder into the joint.
I've been doing "N" s like this on commercial TV and FM coaxes running
1KW+ for over 40 years and have never had a problem with a joint
constructed like this.
I also fan the braid and use a 300 watt gun to tin the braid in a ring
around the dielectric. The secret is a hot gun, and freeze spray
after the solder hardens... that way, no dielectric deforming. You
will get good after a few trials. A second person rotating the coax
is very helpful.
Then I trim the soldered braid with a side cutter and then assemble
the connector. No chance of shorted connectors due to small pieces
of braid ...... and when assembled, and during "scientific testing"
the connector will support over 200 pounds.
