Both the interpretations are valid and compliant.
The "always" enforcement is a direct consequence of what stated in:

"4.8 Keeps and Breaks

Keep conditions are imposed by the "within-page", "within-column", and
"within-line" components of the "keep-with-previous", "keep-with-next",
and "keep-together" properties. The refined value of each component
specifies the strength of the keep condition imposed, with higher
numbers being stronger than lower numbers and the value always being
stronger than all numeric values."

But when the situation is overconstrained, as in the case of overflow,
the resolution of the overconstraints is implementation dependent
(please see 3 Introduction to Formatting).

Thanks,
Fabio Giannetti
