Me too but I can see everyone is missing my point.
TL;DR anything contained in the SID may be omitted when you are cleared on the SID.
@ me next time
The answer is that the clearance is abbreviated. If the airport has a departure procedure, the procedure will likely say on it "expect filed altitude 10 minutes after departure". If it does, there is no need (per the .65) to read it, unless the altitude was changed.
At one of my previous shops the SID actually said expect filed altitude 5 minutes after departure. Pilots would often read back expect filed altitude in 10, even though they were not cleared that way, and we would have to correct them. This was at a class C airport serving 3 majors and a budget airline.
At another one of my shops we didn't even read the initial altitude (which I thought was a bad practice but nothing ever came of it)
