How to read it
The Navy's Builder Advanced course describes sliding doors arranged to slide into concealed recesses when opened; the recess is the pocket. Like other door symbols, this one shows the door's shape and the direction it moves (TM 5-704), so the leaf lies along the wall line and partly inside it.

Look-alikes
A sliding door slides past a fixed panel instead of into the wall, so both panels are drawn in the opening.
