I can reproduce the problem here. The point is that the way you call
file-name-all-completions, it doesn't reach Tramp. Whether Tramp is
involved or not is decided by the DIRECTORY parameter of
file-name-all-completions. It shall be expanded before that check, but
it isn't - I would say it is an error in file-name-all-completions.

However, you can solve it very simply. Apply

  (file-name-all-completions "Splus" default-directory)

This is equivalent to your call, and it does the right thing.
