allways_reuse_session=True does not reuse a session

[nicrobert]

I've been trying to use allways_reuse_session=True (shouldn't it be always_reuse_session?) for a simple DAG that has 3 SASStudioOperator tasks connected in serial.
And it appears that each of them creates a new SAS session (a new Compute pod). So not different than NOT setting allways_reuse_session (allways_reuse_session=False).
Moreover, when allways_reuse_session=True, the 3 compute sessions are not properly deleted.
