I assume he's talking about a variation on the following, which is what SQL Server will create for you, if you create your fks from a diagram for example (which is what I usually do.)

Here the 2 table names are present, and just an incremental number for the FK counter.

If you include field names, you could find yourself on the wrong side of 255 character limit.

'[dbo].[Custodian_SubPortfolio_FK1]'

'[dbo].[Custodian_SubPortfolio_FK2]'

'[dbo].[Dimension_SubPortfolio_FK1]'

'[dbo].[Dimension_SubPortfolio_FK2]'

'[dbo].[Dimension_SubPortfolio_FK3]'
