This answer is yes, a total arrived at with an ace counted as 11 is a "soft total,."
This comes into play with the "soft seventeen" rule that reduces a player's expectation slightly (by 0.2%). This happens with a hand if a 1 makes it a 7, and an 11 makes it a 17. (The two starting cards might have been 3-3, 4-2, or 5-A).
Normally, a dealer needs to stand on a "hard" 17. With a "soft 17," that includes an ace, s/he must redraw, and possibly make a hand higher than 17. This increases the dealer's chance of beating a player who hasn't busted.
If a player has starting cards totalling 11 or higher (e.g. 7-4), an A makes it a "hard" 12, because if you count the A as an 11, the player busts.
