Helping a partner with his call

[youngump]

One from this weekend has been on my mind a while.
I'm behind the plate when R1 tries to steal second. The throw beats her by a good bit and she dives to the outside. From my position (I got maybe a couple of steps up the line to increase my angle), it looked like F6 didn't manage to get a tag on her. Partner calls her out. Third base coach comes partway out to him and yells about a missed tag and then he comes over to me.

He asks me if I saw the tag. I told him that I didn't think she made it from where I was but that he had a much better look than I did. He stayed with the out call.

I'm kind of thinking I should have spent more time talking through what he actually had on the call and why he came to me. Or maybe I'm just overthinking it and I should be content just giving him what I had. Thoughts?
