Flow Control in stored procedures

A newbie question..

If within a stored procedure there are a list of Stored Procedure calls.

Create Procedure spTest AS

EXEC spMyActionQuery1
EXEC spMyActionQuery2
EXEC spMyActionQuery3
EXEC spMyActionQuery4

GO

Assuming each sub stored procedure executes an action query, does SQL Server ALWAYS wait for the current procedure to finish execution before proceding with the next stored procedure? I believe the answer is yes.The answer IS yes :D
