There is nothing wrong with making an argument in this form:
Premise
Proposition
Conclusion
A non-sequitur occurs when your conclusion is not supported by the premise. It doesn't mean that there's anything inherently wrong with the structure of a syllogism; it means that your specific argument isn't valid because you didn't follow the requisite logical rules.
That is not an argument structure, that's just what an argument is (although it's technically just Premise+Premise+(any additional premises) = Conclusion... all premises and conclusions are propositions). Literally all arguments have that structure so to describe that as the argument's structure is redundant at best.
The structure of his argument is (in plain English):
P1: All A have X
P2: B has X.
C: Therefore, B is A.
This is an invalid argument form, as the conclusion does not follow from the premises.
