Depends on what SSD manufacturers call a "write". If touching a block (even slightly) is a write, then a 100MB update could not be so far away from a 100kB word document, depending on block size.
In principle this is true, although it's nowhere near this extreme. NTFS needs to write to six places to create a new file - assuming a 256Kb block size, that's 1.5Mb. Note (for fair comparison) that a 100Mb (to download) update will expand into a much larger 300-400Mb set of writes to multiple files. Assuming the average file size being replaced is 2Mb, we'd have (400Mb / 2Mb) * (2Mb + 1.25Mb), or 650Mb of block writes. So the single 100Mb (to download) update is still 433 word saves.

Word autosaves every 10 minutes. However, the extra versions Apple are proposing aren't likely to cause a whole lot of extra wear on SSDs - most writes aren't simple user data anymore. A single 100Mb update balances 1,000 hours of editing a 100Kb word document, for example.
