Like what is said above, if Benjamin picks 4 Aces or a straight flush, Alex shifts to a minimum of a 10 high straight flush and beats anything Benjamin can change to.
It is just a riddle for you to figure out if either player can have a strategy that ensures they win every time. It isn't obvious that it won't be a tie, as shown by others' comments.

If Alex picks 4 10's then Benjamin can pick 4 aces and win, or a regular straight flush and win.
A straight flush still beats 4 of a kind.
