Why does adding `par` here add vertical space in a different place?

I've been playing around with LaTeX trying to really learn how spacing works in-depth. Here's a silly bit of code that I've been experimenting with:
documentclassarticle
% Draw a raised hrulefill
newcommandhmidrule[1]
leavevmode leaders
hboxrule[#1]1pt.4pt
hfill kern0pt
% Draw a divider with a given ornament in the middle
newcommanddivider[2][0.33em]
parnoindenthmidrule#1#2hmidrule#1par
begindocument
dividerlarge A
%%
hspace*fill
huge This is the First and Last Line.
hspace*fill % <--- Keep this line in mind!
%%
dividerlarge $Omega$
enddocument
This produces exactly the result I'd expect from this: minimal spacing on the top and bottom of the centered text.
Then I put par on this line:
% ...
huge This is the First and Last Line.
hspace*fillpar} % <--- Added `par` here.
%%
% ...
And I expected that no change would occur, since ending this paragraph would cause nothing; the paragraph was already ending there, but I also thought that it could feasibly add some vertical space below the centered text.
However, this was the result: vertical space before the centered text!
I really don't understand why this is happening. Why would adding this command after the text cause spacing before it? Could it be that LaTeX trying to format this as paragraphed text? If so, why didn't it add space there before I added par?
Any other feedback would be greatly appreciated.
I'm compiling my code on Overleaf, with pdfLaTeX. The same result occurs with XeTeX.

The difference is that with par the paragraph is set with the baselineskip relative to huge, whereas it isn't without it.
If you want to control precisely the spacing between the decorated rules and the title, the best is to disable the interline spacing at the transition, with nointerlineskip.
I provided a different definition of divider that avoids the need to guess a dimension.

That's a very clever way of defining the rule! I appreciate the explanation very much.
