I have not been to MIA for many years except for a few times recently and not in the X terminal pocket at all. We were pushed from gate X to spot Y. When the tug turned us loose all I saw was spot Y still ahead of us. Ground control told us to wait for an aircraft to pass; then taxi on taxiway P to [Runway] 8R. I thought it was prudent to continue to spot Y while we wait for the aircraft to pass. On the way to Y I noticed we were encroaching on taxiway P. I stopped to let the other aircraft pass. I did not understand how I could have gotten to close to taxiway P while still short of spot Y.  I was using the 10-9 page and did not see an error. Upon further review using 10-9 page I saw there are three taxi lanes that are only depicted on this page. Spot Y lane to the North; spot Z lane to the South and one in the middle that does not lead to either spot. There is a large Y painted on the ground further out that is not depicted on any chart. When the tug turned us loose I believe we were stopped on the middle taxi lane very close to the hold line. The hold line and the close in spot number were not visible from where the tug stopped us. Neither of us saw them. The Y painted further out is the only one visible from my vantage point. If not familiar it is a very confusing situation. Even though I reviewed terminal and taxi charts this still happened. Next time into Miami I will be more aware of ramp layout.[Suggest] depicting the hold line on 10-9 chart and tug driver not stopping aircraft so close to hold line that it cannot be seen in wide body aircraft.
Pilot reported confusing ground markings leading to a spot out of the terminal area in MIA.
