When a person posts a trade for a quantity greater than 1, that trade could get filled by multiple other trades. In other words, if the original order is for a quantity of 10, it may fill with one order of 3, another order of 6 and another order of 1. These would show as trades of 3, 6 and 1 by default. When you set the option to "Combine Trades Into Original Summary Trade", it shows the trade as a single trade of size 10.

From this, you can see how you would end up with more large volume trades when you enable the option.

When Combine Trades Into Original Summary Trade is set to yes, are orders only combined at one price level? Or are they combined across multiple price levels (i.e., setting combines market orders that sweep various levels)?

The description of this setting in the documentation says: "Trades which are combined into a larger quantity summary trade are always at the same price. A summary trade only consists of one price." I read this to mean that they are only combined at one price level, but not completely sure.

Ok. When using ACSIL and the Unbundled Trade Indicator member of the s_TimeAndSales structure, tracking the total volume that transacted between a first and last unbundled trade to simulate what the Combine Trades Into Original Summary Trade setting does in a custom study, does the same occur? Phrased another way, do the first and last trade of an unbundled trade always occur at the same price level or can they span various levels?
