the meaning of "Bob's your uncle" is roughly equivalent to presto"

[chance22]

I've read an article about the difference between American English and British English. One sentences reads,

I learned that when someone says to me, "Bill, you're a brick," they are not really likening me to an inert building material but complimenting me on some manifestation of solidity and reliability, that "Bob's your uncle" is roughly equivalent to presto. I learned all this, and it took years, and I still get confused.

I don't quite catch the second example. Does the author use this example to show the difference of pronunciation between American and British English or to continue illiustrating unexpected meaning of those words"Bob's your uncle"? Is presto here of the same meaning as is used in music?

Looking forward to your explanation.

Hey presto is used as a way of highlighting a result- magicians can say it just before they reveal the results of the trick, so in that sense it is similar to Bob's your uncle, but it is more theatrical, so they're not identical. Bob's your uncle means that you will achieve a result, while hey presto is for demonstrating a result IMO.

So the original ''"Bob's your uncle" is roughly equivalent to presto' is misleading. It should have been '"Bob's your uncle" is roughly equivalent to "[Hey] presto"'. Nowadays, I hear 'bingo' or 'voilà' more often than 'hey presto' in this sense.

I also find find English British hard to understand. Thanks for the answer. I'm learning as I read all these posts.
