I believe it's not expected because in Pluto order of cells should not matter. They write:
> Cells can even be placed in arbitrary order - intelligent syntax analysis > figures out the dependencies between them and takes care of execution. in [Readme](https://github.com/fonsp/Pluto.jl). But reality is different. Or you can create notebook with cells a = [1] # Output [1]. a[1] += 1; # No output. a # Output [7] (after evaluating the second cell 6 times) a # Output [8] (evaluate the second cell one more time and then evaluate this cell) Run here is a [picture](https://postimg.cc/rKXQZKBX).
