Consideration for sec 56(2)(viii)(b) of income tax act

Sir, 
when the sale of property and agreement of sale are different, section 56(2)(vii)(b) says that full or part of consideration should be received by any other mode than cash on or before the date of agreement. My query is if a person is partner in a construction firm. Now out of his investment as partner in that firm, if he purchases a commercial unit from that partnership firm, would it not amount to consideration being paid before the date of agreement in a mode other than cash ??
Pls suggest with some case laws.

Thanks
