@PatzerGareBear13 As @srchernik15 correctly pointed out, h6 is the by far most common move after Be2, so white gives himself the option of Ne4.
Because of that h6 is not actually that good (it's ok, but not really critical) against Bd3, rather Nd5 or the by me recommended Ng4. The idea is that if black gives white enough time white can keep the Knight on e4 and move the Bishop away later (or even sometimes play b3 Bb2) and black might not have that much compensation.
