This doesn't answer your question, but specifying the arguments to echo
using replacement strings works as you expect:
parallel echo {1}{2} ::: {a..b} ::: {a..b}
My guess would be that Parallel assumes the arguments following ::: are
actually separate arguments to the command given, so they should be
separated by a space. So executing `echo a b` would give the same output
as parallel.
