Game Mechanics: Rock golems in hole not behaving properly while rooted

[Tudar]

shaman has rock golem rooted, rogue at max (or near max) melee range.

rock golem faces the shaman, bash's him occasionally, but regular attacks he turns to swing at rogue and right back to shaman.

at 00:15 Radston re-roots golem to show its rooted.
at 00:23 Rock golem hits Rogdar for 45 points of damage, while still facing a sitting, closer Radston
at 00:31, 00:41, 00:46, 00:55, 01:03 - same behavior

Odd that the rock golem will bash the closer target, but swings on the max melee.
