I have seen a few dozen Texas Confederate pension applications. The ones who served in both the TST and CSA always listed a CSA unit, but I have seen a few approved pensions from TST soldiers. One example is Hilliard Seamans, who was born in 1845 and spent most of the War serving under his father in Captain William Seamans Company. One of his witnesses was his older brother, one of those who served in both TST and CSA units.

Texas State Troops were often mustered into CSA units for 6 month periods. For example, they were sent to the coast to build and defend fortifications on several occassions. They were also frontier troops. Depending on the time and place, the lines between TST and CSA command could be rigid or confusing.
