Need help with btrfs send | btrfs receive

I have 3 subvolumes I want, so send from one disk to another.

btrfs send --help shows:

-e               If sending multiple subvols at once, use the new
                     format and omit the end-cmd between the subvols.

and btrfs receive --help shows:

-e               terminate after receiving an <end cmd> marker in the stream.
                     Without this option the receiver side terminates only in case

I understand the words, but not the sentence in general. I've checked man 8 btrfs-send but it is the same.
At the end I don't know If I should use
btrfs send @ @home @cache | btrfs receive
or
btrfs send -e @ @home @cache | btrfs receive
or
btrfs send @ @home @cache | btrfs receive -e
or
btrfs send -e @ @home @cache | btrfs receive -e

And can I use
btrfs send @* instead of btrfs send @ @home @cache?
