Yes, the names act as comments about intent.
Such comments can be misleading about what the code actually does.
Since I think you're very interested in the human aspect of this I suggest you
try to find information about how master chess players remember chess boards. As
I recall, they find it really difficult to remember random boards, while boards
that represent actual chess games are remembered at a glance. Indicating that
what's remembered is at a much higher level of abstraction than piece positions.
