I tried manually assigning an alias with:

select a.field1, a.recno("a") as RecNo1,... from table1 a, table2 b where ...

That only returned the correct recno() for alias B, the recno returned for alias A was always 1. Interesting. I tried doing this with deleted() as well trying to resolve another problem with parameterized views not bringing over the deleted marker if set deleted is off. :(
