The classmate has incorrectly applied this theorem:

If two lines are cut by a transversal so that alternate interior angles are congruent, then the lines are parallel.

That theorem applies to exactly three lines: the two lines and the transversal that intersects them and forms the alternate interior angles.

The alternate interior angles must be formed by exactly 3 lines in the posted problem.

If the diagram looked like this, then the classmate would be correct. The lines would be parallel.
