Yep. More than one way to name them, plus bonus material of other goodies (tools are always good!) that do the same or similar things, and other ways to do the same or similar things.
"Post" and "leg" vise seem interchangeable but "foot" seems to refer to something where the work is clamped via foot pressure on a lever. Would be handy where frequent position changes of the work are required.

Regardless, as you say, it's all good. The English vocabulary is arguably the largest in the world. The OED used to be 20 volumes and something north of 600,000 entries.
