Is it possible to make parallel at the same y in sequence diagram?

[maple3142]

For example, on https://sequencediagram.org/

Alice->Bob: Message 1
parallel
note over Alice: note 1
note over Bob: note 2
parallel off
parallel 
Bob->Alice: hello 1
Bob->Eve: hello 2
parallel off

shows

And the equivalent in mermaid would be:

sequenceDiagram
    Alice->>Bob: Message 1
    par
    note over Alice: note 1
    note over Bob: note 2
    end
    par
    Bob->>Alice: hello 1
    Bob->>Eve: hello 2
    end

I would like to make those two notes and two arrows actually shows on the same y instead of how currently mermaid does that. Is it possible in mermaid?
