Going through his lawyers and explicitly saying that this is a confidential legal document is a way to get press for his case while not technically violating the conditions.
On the other hand, I'm doubtful that there is sufficient incentive for Assange to try such a workaround. My Spanish is weak, but it looks like the last few lines of the agreement say that it can be unilaterally modified by the Embassy at any time. This would seem to negate any advantage of adhering to the word but not the spirit of the agreement.
