You are right. I had the same observation at minute 11:27

Sorry, which is right? I know ifThrown is lazy, I'm curious about
the "amount" of the expression that is evaluated lazily.
a.b().c().assumeWontThrow vs. a.b().c().assumeWontThrow

+- lazy? +- lazy?
The video seems to say "don't use lazy functions with UFCS
because you might think the lazy part gets evaluated first, when
it does not". Seems reasonable, although I don't know it's any
different than assumeWontThrow(f()).
