Glad you had a good time! Lake Travis is sure not blue water diving, but has it's own rewards. Sounds like y'all followed the Lake Travis buddy separation plan, 'continue dive and keep eye out for buddy until agreed upon time interval or turn pressure is reached, then do safe ascent and meet at entry/exit point', not too different from standard separation except for the variable and often extended time interval, which varies according to less experienced buddies comfort and experience level, maybe 5 minutes, maybe 50, for the doubles set even more.
Hope our fresh murk didn't ruin you for salt hopefully you have just added to all the places you now consider diveable Sorry I couldn't get out and join y'all, shout out next time you come up this way for some muck diving.
