Are they doing this just to confuse me?

My old friend Airfix seem to be throwing me something of a curve ball. Are they testing my sanity? (see below, two very similar tins [yes/no] delete as applicable, so how do you open them):

But behold, the one on the left "screws off" (if you pardon my expression) from the top, despite having a 'fake' lid on it, while the one on the right "pops off" with a flip off lid (see below, which has totally confused me):

No, but wait for it the one on right also "screws off" but from the bottom (see below, dual action):

What the?

Life is hard enough without this additional taxing mental strain while I am trying to relax! Oh, and despite the new one despite being taller, it only contains 12ml, that's 2ml less paint than the shorter/wider one on the left (which had a capacity of 14ml)

:(

And I thought model instructions could sometimes be hard to understand!
