OP says "Sentinel Alan" That was not Alan when "master of the Starheart". His days as Sentinel were when he was powered ONLY by the green flame. The "good" magic that separated itself from the Starheart. In short massively less powered. He still had the wood weakness then because the power of the "green flame" was the power of life and wood was part of the green so his power couldn't work against it.
While "sentinel" in GL corps quarterly he faced the Starheart (which was not his power source) after a mystic GL from a far space sector sought him out. When he did he dispersed it across the galaxy/universe. he didn't "absorb it" till much later.
If you recall in JSA (90's Johns Goyer run) when Mordru said a "moral wielding the starheart" Alan corrected him and said "green Flame". It wasn't long after that he took back up the mantle of Green lantern and let the "sentinel" name go.
Just saying
