Yeah. York did understand her that way, on both accounts logical and illogical. He understood the weirdness in her head, to a degree, and accepted her for it?
And still he wondered if she'd leave. Why would she?
York was met with more whining protests and feeble kicking until she went a bit limp. Even when they went into the water, she stretched with both hands down just to see if she could touch it. Which she couldn't, thanks to York's height. His back seemed to go on for miles...! It made her laugh.
"Your demands are not fair! I'll freeze to death and you cannot swim!" He couldn't very well save her if she was too far out and he drowned on the way there.
