Ext4 is getting this information from the block layer. Specifically, it's calling part_stat_read(bd_part, sectors[WRITE]) to get the statistics information it uses to caluclate how many kb have been written. I'm not a block layer expert, but it may very well be the case that TRIMS are being counted as requests. Requests are categorized as either READS or WRITES, and I don't see any special casing for non r/w requests in block/blk-core.c.
