The limitation doesn't apply to Numerical Transcendence, because numerical values are considered essentially meaningless.
Infinity and Zero mean the exact same thing to the user, so trying to apply a limitation regarding whether or not they can understand their power doesn't really make a sense. Since its a literal none issue for them.
The power doesn't have limitations, so please stop trying to think of ones for it. Especially ones that cannot and do not apply based on the overall capabilities.
