Yes, if using > 1 session. It is the same considerations as when you need to use TPump serialize. The session should get row hash locks and
if there is a good unique PI with no nupi dups or hash collisions and no SIs or JIs, then the chances of block/deadlock are lower. If it is
nupis or there are hash collisions or SIs or JIs then there is possibility for for blocking/deadlock.
In general, I would recommend operating like tpump--commit each request and don't let transactions span requests.
