Not sure if this is what you're asking about, but:

Code:
for i in *.mkv *.webm

and

Code:
for i in *.{mkv,webm}

generate the same list of files, although the syntax used to describe the pattern to be matched is slightly different. The bracketed notation is just a compact way to say either file extension will do.

It's a handy way to avoid retyping the common elements of two or more arguments. E.g.,

Code:
cp original{,.bak}

expands to

Code:
cp original original.bak

Apologies if I've misunderstood your question and explained something you already knew!
