Justice Thomas was “evading” Puerto Rican born Chairman Serrano's presidential eligibility...Obama’s name never came up.

From the post in your link:
"This is part of the transcript of the exchange between Congressman Serrano and Justice Thomas.
There was no discussion of Obama, and there is no way of knowing if Thomas was thinking of the president or his eligibility."
SERRANO: So you haven't answered the one about whether I can serve as president, but you answer this one.
THOMAS: We're evading that one. We're giving you another option.

I can see both points of view on Justice Thomas' statement. Given the boiling controversy over Obama's eligibility to be president, it's understandable that some people would come to the conclusion that Justice Thomas was referring to that.
Did he use this unique opportunity to obliquely refer to the Obama eligibility issue? I don't think there's any real way to know.
