Exactly. The first character that matches in the trailing .* is a quote.
As I said, the leading and trailing .* are needed to "match away" the entire line. Otherwise only the matching portion would be substituted.

Now to your second requirement. Can give a headache even for experienced guys.
In your example the ' is a problem for the shell, in which you call
There is no problem if you save the sed code in a separate file and run it with
And the contents of the sed-script
You can add another match in a second line
but it won't match if the first match was successful and the input line was substituted.
It is necessary to save and restore the line.
Another aspect is greediness. The * wants to match as much it can. A leftmost * is most greedy.
That means /.*'branch'/ matches the rightmost 'branch'.

Last but not least, the shell method to print a ' within a ' ' string goes like this
Actually it is a concatenation of 'left' and 'right' with a \' in between.
For an embedded sed script it is enough to remember to exchange each literal ' by '\''.
