It would make no sense to detonate all bombs in the tube system - very little for the media to photograph so less of an impact. The second bomb attmepts reflected this - 3 in the tube for maximum collateral damage (due to the more damaging nature of an explosion in a confined space) and one up top for the front pages of the papers.
Interesting that some people are claiming the calls were 'panicky' - how do they know? All they actually know is that three calls were made. Imo, it's more likely that he was the mastermind (or at the least, the cell team lead) and was checking to make sure they'd not re-emerged from the tube having chickened out before detonating the last device.
