The main difference is that submodules are entire repositories, while in svn you can take sub-trees as externals. The difference you mention is not really one, because you can do the same in svn using 'foo -r1000 svn://somerepo' and have it fixed to one revision, just like git does. It's a much saner approach anyway to avoid people having out-of-sync versions of the externals.
