Nope, what was said in its correct context was this:

I'm not saying that. I'm saying that the property does not always
uniquely define a median ("*the* value", emphasis mine), and therefore
cannot be used as the definition therefor. There are some sets, such
as {0, 1}, where every value between 0 and 1 (including both endpoints)
is minimum.

Minimum clearly refers to the expression being minimised by pamelaeffluent. You've been confused by vc misunderstanding repeatedly, stretching the thread out, and separating that single sentence from its original context.
I'd forgotten that vc's exchange with me started right from the beginning with a demonstration that he's too thick to understand simple concepts.
