In view of your logic, let me tell you about my situation recently
when I tested a piece of coax on which I installed on connector.

There were already two connectors on the coax and I removed one that
was crimped and had slipped. I put on my connector and tested it with
my radio, no signal. Hmm, I needed to check the wire.

1) I tested the center conductor and the shield on the connector I
just installed... Short. OOPS!

I cut off the connector and replaced it.

2) Tested the center conductor and shield on the connector I just
installed... Short. OOPS again.

3) after cutting off my connector again, I tested the other connector.
between the coax and shield. Open. Great!

I soldered on the connector for the third time.
4) tested the center lead and shield of my connector... SHORT! Hmmmm

5) I cut off my connector and tested again. Open ?????

I tested the other connector again. Open.

ahhhh. I tested the center conductor from end to end.... OPEN!!!

I tested the center conductor to the shield on the end where I was
installing my connector.... SHORT!!!!

Time for a new piece of coax....

Sounds like too much heat.. You may be melting the clear jacket
and shorting the pin to shield. Be careful using too much heat when
soldering the shield. Sounds like you have a manly soldering gun..

Sounds to me like the connector he didn't replace had an open center pin and a shorted braid.
Remember to make both short and open checks at both ends.
