It must be PQWL ..and it means that the quota of many stations is pooled into a single WL number ..so VSG to LONDA , VSG to Belgaum , vsg to Pune will have same WL in sequence even though quota of seats may be different for each of the stations..so for ex : quota of seats from VSG to Londa is 10 and vsg to pune is 50 ..so as soon as the 10 seats of londa gets filled PQWL 1 starts while seats to pune at that moment may still be available like in your case ..but the PQWL will keep on increasing if people keep booking in the vsg - londa section ..say suppose now the PQWL increased to PQWL 69 and now vsg - pune availability came down to 5 and you booked 6 tickets , so vsg - pune quota 5 seats were given to you...
more... and now the PQWL for pune also started but it will start from PQWL 69 and not PQWL 1 since the WL quota is pooled between different stations...hope its clear !!!
