Correct use of "that of"?

[universe610]

Hello,

I know the phrase "that of" is mostly used to make comparisons but is the following also a correct use of the phrase?

You committed your life to that of an educator.

Thanks in advance.

Welcome to the forum.

No. That doesn't make sense to me. If someone said it, I would assume they meant either:

You compared your life to that of an educator.
You committed your life to being an educator.
