That has to do with sh(1) globbing rules. The shell did exactly what you told it
to and expanded _everything_ in the present working directory. Then it attempted
to move all of that inside "5mode-com". But moving a directory inside of itself
is invalid, so it errored.
This happens on Linux too (demonstrated using termux on Android in this case,
but I guarantee you can reproduce this elsewhere).

dir1 file1 file2 file3
.../tmp/tmp.7WQbdeMg3C $ mv * dir1/
mv: cannot move 'dir1' to a subdirectory of itself, 'dir1/dir1'
