Why should it be that rather than (x - 4)(x - 3)(x - 2)(x - 1)? The two expressions are equal.

That's completely subjective. You might prefer it written like that, but that doesn't mean it's how it "should" be done.

(x-4)(x-3)(x-2)(x-1) is the 'glass half-empty' version.

(x-1)(x-2)(x-3)(x-4) is the 'glass half-full' version!

Reminds me of:
an alcoholic somehow pleases a genie who says:
"you get 2 wishes; what's your 1st one?".

"I'll take a bottle of tequila that fills up automatically
after I drink from it".

Genie: " POUFF! here you go..."

The alcoholic takes a drink...bottle fills up after...

Genie: "and you 2nd wish?"

"I'll have another one of those bottles"!!

thanks to all of you for your efforts, the source of this equation can be solved in a different way, so there's no further need. Anyway, thanks
