Yep. One tries to guess the format from the strings passed as
arguments (e.g. you can use both 'protein' or 'aa' for the protein
alphabet) and then reads the file. Internally all it does is to call
the other method with the correct integer argument.
The methods in any class called FooTools or BarTools in biojava are
convenience methods, often built from other lower level API in
biojava.

It's fine to use either. Formats are not linked to alphabets per
se. It is just convenient to have both pieces of information stored in
a single value (and int) for reading files. There are lots of possible
alphabets and file formats so it's handy to be able to calculate
identifiers for all possible current (and future) combinations.
