In this reaction, carbocation intermediate is formed. When bromine react with aluminium bromide, bromonium ion is formed. Since aldehyde (CHO) is a electron withdrawing group, ortho and para position are less electron density. So ortho and para product are not formed.
The double bond of benzene ring attack the bromonium ion and a carbocation is formed (intermediate) and a proton is loss and product is formed.
