Well, there still are tiles for TWO ramps. One for high raised jungle and one for raised jungle. But only the ones from left to right, that's true. It should be possible to do some neat things with some playing with the tiles, to me this ramp looks like it leaves quite some options.
My screen was made in SCMD2 in unit placement mode. The darker areas are unwalkable. Now compare the walkable area with the size of that zergling...
The ramp is as wide as 2 tanks/goons/lurkers. The only unit that would not fit twice is the ultralisk.
