I don't know what you mean by "more visual".

In my opinion, when comparing a variable to a constant, it's more natural
to have the variable on the left and the constant on the right, so that's
one strike against this code.

Another strike is that the code isn't consistent with itself; it puts the
variable on the left in the first comparison, then swaps to the right for
the second comparison.
