I'm not sure what you mean.

You wrote:

    copy ${mountpoint}/MakeMKV.app ${mountpoint}/MakeMKV.url ${worksrcpath}/

This works fine and copies the directory MakeMKV.app and the file MakeMKV.url into the directory ${worksrcpath}.

But since you don't need MakeMKV.url it also works fine to just write:

    copy ${mountpoint}/MakeMKV.app ${worksrcpath}

The copy procedure does not behave differently depending on how many source items there are, and it does not be have differently depending on whether or not you put a slash at the end of directory entries. It does not behave differently in destroot than it does in other cases, and the only thing I could find in the Tcl documentation about copying across filesystems is that symlinks are only preserved when copying within a single filesystem, which isn't applicable here since you're not copying symlinks.
