Should strikers end umpire explain why he calls a no-ball?

[squarecut]

In a recent Ladies match the strikers end ump (SEU) called no-ball, swiftly followed by a call of no-ball by the bowlers end ump (BEU).
I should explain that the SEU was appointed by our opposition, and was relatively experienced,
whereas the BEU was the dad of one of our players, and was knowledgeable, but far less experienced.

Well there was a call of no-ball for the next ball from the SEU, followed by a certain amount of head-scratching, and then for the following delivery there was a third call of no-ball from the SEU, after which our Ladies captain moved her square leg more towards mid-wicket.

Of course the call was for more than 3 fielders behind square on the leg side.
In conversation afterwards it became apparent that the SEU was being quite strict in the application of the law - ie the girl in question was pretty much square, but some part of her was the wrong side of the extension of the popping crease.
"Our" BEU had perhaps confused the issue by confirming the call of no-ball on the first occasion - he said that he thought the SEU was indicating a no-ball beamer, whereas the SEU said that it was a call, not an indication.
The SEU also averred that he was not allowed to indicate the reason for his call.
This wasn't happily accepted by our skipper.

I wonder whether umpires generally would indicate the reason for a no-ball call, as this then would stop any misunderstanding.  I was surprised that the SEU wouldn't voluntarily give the reason for his call, but he is a county-level assessor, so I'm sure he knows more than I do.

What are your thoughts?
Thanks

I will always say why I have given a no ball. I don't see why you wouldn't !

I'd agree - providing the question's asked politely, I'm always prepared to explain (not discuss / debate) any of my decisions.

I totally agree. You don't have to volunteer the information if you don't wish to—although for unusual calls I still would—but if you are asked, why would you not simply answer the question? You just invite mistrust and disrespect otherwise.

The usual calls are for more than 2 behind square or the keeper encroaching and not staying wholly behind the stumps. I tend to indicate what's happened by gestures - pointing to the fielders or miming the gloves coming forward. For the latter the keeper quickly gets the message.

The bowler's end umpire should repeat the No Ball signal (Law 14(a)(ii)) - something very rarely done - so I think it's a good idea for the umpire at the striker's end to indicate to his colleague why he's made the call.
