Maybe he meant:

You have a Greater Lens installed on an Item #1 giving you conversion 1.75%

If you install Eidolon lens on the Item #1 your conversion rate is 2.25%, where the increase is only 0.5%, but

if you install Eidolon lens on an item #2 your conversion rate becomes 1.75% + 2.25% = 4%, which also gives you one more potential item to play with to gain focus. So 0.5% vs 2.25%.

Ofc if you have lenses on every single item (you'd actually use) then ofc replacing Greater with Eidolon is a no-brainer. And ofc if you plan to actually play majority of your game time with the same item #1 then replacing is beneficial too, but if you switch items around a lot it is more beneficial to install it an another item.

But who knows, we will never know.
