I get similar feedback from riders new to trail braking. The handlebar will feel heavier with more braking before the bike is leaned over. After the bike is leaned over (~30% lean) the brake will cause the bike to lean easier due to braking and centrifugal forces changes. Also, if you look at the tire profile, it's flatter above the shoulder area, more curvy closer to tire edge which causes the bike to lean faster after past a certain lean angle.Yes. That does answer the question.
However when trailing the brakes does it require less handlebar pressure? Most riders report that under trail braking the steering feels heavier meaning more resistance at the handlebars. Along those same lines most riders report that under throttle the handlebars feel lighter.
Finally, one of the most common reasons why a bike is harder to turn is not having proper front tire PSI. I.e, on my front I run SC1 38 PSI or SC2 36. 1-2 PSI lower in the front will make a difference.
