Good point. In those cases, the analogy breaks down. Merriam-Webster offers several definitions for "parallel", though the only definition with a temporal connotation is the definition related to computing: "relating to or being a connection in a computer system in which the bits of a byte are transmitted over separate channels at the same time" Meanwhile, "concurrent" references "parallel" as a synonym. Perhaps the terms are rather arbitrary after all, and we just need to get comfortable with their less-than-perfect assignments.
