According to me, it may be because of the electron withdrawing effect of 2 -OH groups. Since they are in meta positions with respect to each other the inductive(-I) effect is a bit predominant and this makes the H atoms between the 2 Carbon atoms carrying -OH more acidic and hence gives iodoform test... (Remember presence of acidic H is important in deciding)

How does an acidic hydrogen help in it?? Please explain Also doent it lose aromaticity by undergoing iodoform. IS such a thing possible??

resorcinol undergoes keto enol tautomerisation ,due to this the CH2 group between the OH groups is activateted,and the hydrogen become acidic,so it can give iodoform test easily.

and yes aromaticity will be lost,but it will tautomerise only under either acidic,or in this case basic
