UML Element Description
Weak Sequencing (Combined Fragment)
Weak Sequencing (Combined Fragment)    
A weak sequencing interaction operator (signified by the value of seq) defines a combined fragment where the order of event occurrences within one operand are significant and event occurrences on different lifelines can be interleaved, but event occurrences on the same lifeline, in different operands must occur in the order of the operands. Thus event occurrences in the first operand must occur before event occurrences in the second operand if they are on the same lifeline.
