I don't think the passed dates are typos. I've seen this before in direction hearings orders. Basically, I believe if both parties have missed deadlines for providing documents, the directions hearings seem to release 'back dated orders' to keep it all official. BTW, this is the impression I've got, not legal knowledge. I think that applies to the following:

2. The defendant be granted an extension of time to 27 February 2015 to file and serve its amended
defence.
3. the plaintiff be granted an extension of time to 4 March 2015 to file and serve its amended reply.
4. The defendant be granted an extension of time to 11 March 2015 to file and serve its further
list of documents.
5. The plaintiff be granted an extension of time to 18 March 2015 to file and serve the statements
of Mr Stephen Frederick Johnston and Mr Robert Paul Tolliday.
6. The plaintiff be granted an extension of time to 24 March 2015 to file and serve the statement
of Mr Anthony Dean Lethlean.

I would say these were all the dates when the various statements and replies were served.
