It's not expected as such, but it is reasonable. What's happening is
that Haml takes everything to the left of the =, assigns a variable to
it, and calls to_s. When you evaluate
foo = "bar", "baz"
foo becomes
["bar", "baz"]
Calling to_s on this gives you
"barbaz"
which is the behavior you're seeing here.
