Most people do it, I guess, because the fresh ice is more pretty (if the
quality is good). The fresh cubes are larger and have sharper corners.
The dilution is due to the melting of the ice. When putting the drink from the
strainer into the glass the amount of further dilution is not much influenced
by using new or old ice.
Both need to melt in order to cool the drink. Also, because the drink is cold
the amount of any further dilution isn't as big as the initial 1.25oz.
There might be some small influences of varying direction: The new ice might
need to melt a little bit less because it is colder (technically, in some
cases, the old ice could be colder than the new ice). The new ice might
introduce a small amount of liquid if it was kept badly and is in a state of
melting (which means it is covered with a small layer of liquid).
