Bug with lag and shapeshifting?

<677hp 419m 727mv 24350 civilized> You drive your axes into both sides of a grizzled ram's body. Your brutal attack MUTILATES a grizzled ram! Your brutal attack EVISCERATES a grizzled ram! The bellowing of a ram startles you. A grizzled ram is writhing in agony. <677hp 419m 727mv 24350 civilized> The edges of a grizzled ram's being stretch and twist and he becomes a huge anaconda. A huge anaconda's bones creak and snap as he shapeshifts. A huge anaconda's shapeshifting wounds him. A huge anaconda dodges your cleave. A huge anaconda dodges your pierce. A huge anaconda dodges your cleave. A huge anaconda is writhing in agony. <677hp 419m 727mv 24350 civilized> A huge anaconda dodges your cleave. Your pierce MUTILATES a huge anaconda! You fail to get in one more shot as a huge anaconda flees. A huge anaconda leaves east. A huge anaconda has fled! Is that the second round, when he flees? Because it just strikes me as odd that he can shift directly after I'm pincering. I know he isn't using the bug, he was attempting to regen.. Thanks
