multiline table headers and formula references

I am making a table for people who may not be tech savvy and would like to use my own line breaks in the header row for their readability, despite column width. For example:

MM SAME AS PREV

When I do so, the references in formulas end up inheriting the line breaks as well, so the formula line looks like:

=IF(NOT(IS BLANK([@[MM SAME AS PREV]])),[@[PREV MM BLI]],"")

The MM SAME AS PREV column is meant to be used a checkbox by the end user, and if "checked" with any text, the cell in question autofills from the PREV MM BLI column. Other formulas are more complex, so those formulas show up as 3-5 lines and are accordingly much less readable. Is there a way around this, or do I just need to choose between readability for author vs readability for the end user?
